OS X :: Connecting Router To Second Ethernet Port?
Dec 2, 2009
Can I connect a wireless router to the second ethernet port of my MacPro? I have the main ethernet cord from the modem connected to my ethernet port 1, then I connected my router to my computer through ethernet 2, thinking that it would broadcast the internet connection. However, it is not working. The router is broadcasting, but the internet isn't working (and the light indicating internet connection on the router is yellow, not green). Is this something that isn't possible? Or do I need to change settings (not just plug and go)?

I was just wondering if any other macrumorsmembers have been in the situation where there's no wifi, no decent 3G, but ethernet ports available to use, but you don't have a computer handy? Would it be possible that you could create an ethernet cable one end, dock the other, and literally connect e.g. an iPhone into the ethernet? At my place of work, there's no signal (dodgy GPRS/flakey Edge), some wifi, but in halls of residence, you get 1 ethernet port, and you can't put a wireless router onto it. It would seem that it would be an interesting solution, if it was possible.

At the moment, I have an ADSL modem/router (1 port) connected to my switch (ethernet port 1 on the server and all my clients are also connected into this same switch). ADSL router has IP address 192.168.2.222 (assigned manually - outside my DHCP range). X Serve operates as DHCP for everything else and I put the default gateway as 192.168.2.222. Internet works fine on all computers (including server). But I want the ADSL modem/router to be connected to ethernet port 2 on X-Serve (not straight into the switch). If I just unplug the ADSL router from the switch and plug it into port 2 of the X-Serve, the server can access the internet, but all clients can no longer. Anyone have *any* clue how to fix this?! It doesn't seem that complicated, I feel I have done everything right.

How many of you would like to see a HDMI Port? Why the miniDisplay port? Why not remove ethernet jack and miniDisplay port and replace it with a HDMI port. That way one HDMI cable feeds digital video AND audio. Am I the only one thinking of this?

I just got a MacBook Pro (bootcamp with Vista) and I want to transfer all my old files from my PC desktop onto my new MacBook. So far I have connected both computers to a router via ethernet and copied some files, but I have only figured out how to do this while the Mac is bootcamped into Vista. I have the computers hooked up correctly, but what do I do within Mac OS X in order to transfer files from my PC desktop straight to OS X. So far I have copied to Bootcamp Vista, then copied from that to my main OS X partition, but this is way slow. I want to copy directly to OS X.

So, the built ethernet will not communicate with the N+ Belkin router I just bought. I don't think the ethernet cable is a crossover (plus it worked when plugged directly into the cable modem, it also worked when setting up the ibook) and when I plug both ends into two of the four slots of the router the "wired" light comes on (according to folks at Belkin this proves my cable is good).
The Belkin folks are blaming my ethernet port and believe there is something I could do but can't help reconfigure the ethernets IP address? Just to double check, I hooked up the belkin with my ibook G4 (Dual 533) and it worked fine through the router. The ibook has airport, do I need Airport in my old G4 desktop? Can't I just leave it connected to my router (if it worked). The whole point is to get two computers on line at the same time.

My iBook G4 is having network issues. Since waking from sleep, it will connect to my Airport Extreme base station, but I can't access the web, or access the router from Airport Utility.
Things I've tried so far:
*Rebooting
*Resetting the router to factory defaults
*Swapping out the router for a Linksys
*Clearing out network passwords from Keychain
I doubt it's a hardware issue, as everything works in Tiger (booting from an external drive).

Basically, I have a wireless router in my house that my Mac Pro connects to from a seperate room. I have an xbox 360 in my room with the Mac Pro. Without buying the $100 360 wireless adapter, could I configure it so I could run my 360 into my Mac Pro's ethernet port and piggy back off of my Mac's wireless connection to get on Xbox Live?

I used the MacRumors Buyer's Guide for several months to find the best time to buy a MacBook. I'd never had a Mac before and found it to be so valuable. I hope someone in the forum can be as helpful as the site has been.
Yesterday I bought a new MacBook Pro 13" and as a store option the RAM was doubled to 4GB. Everything has worked well so far, in both OS X and Windows XP through Boot Camp, except for either OS accessing the LAN cable on my home ADSL. Both my portable modem (EMobile network in Japan) and the wireless seem to work with no issue, and both OS will recognize the ethernet port. I'm concerned that perhaps the ethernet adapter was modified when the store installed the memory.
I can remove the ethernet cable from one computer (where it works without any settings changes on my Windows notebook) and plug the same cable into the MacBook and it will not be recognized. The Mac OS error is that no cable is inserted.
However, as it's my first Mac, I didn't know if perhaps some new settings are required to make things work smoothly. Is there any DNS settings etc. that must be set for it to connect? Also is there some kind of connection diagnostic that will specify the location of the error in the machine? I'd like to exhaust any option before shipping this back to the store to be repaired or replaced.

First I have an early 2008 Mac Pro with 2 Ethernet ports. Port 1 works but port 2 doesn't. Do I have to lug this BIG machine into an store or do they come to the house and fix it. I have the 3 year Apple Care. The closest store to me is 75 miles away.

forwarding ports to my semi-new iMac. I got my iMac back in September and I've been trying to forward my ports since then but have unsuccessfully done so. I've followed every guide i can find but still i dont know what i've done wrong. I have a Belkin N+ router. I think that I managed to give myself a static IP but from there i can't get anything to forward.

I'm looking to add a second ethernet port to my MacBook Pro using this product designed for the MacBook Air: [URL:...] Comments on the Apple site indicate that the device can be used with other computers, but I want to make completely sure it's going to do what I want it to do before I make the purchase. The reason I'm looking to do this is that I want to link my MB (via ethernet) to another laptop running Windows 7 Ultimate and use the Microsoft Remote Desktop Client to operate programs installed on the WIndows machine. The catch is that the internet at my current location (a university accommodation building) is also supplied by ethernet LAN and has some kind of detection system that prevents unauthorised routers from accessing the internet. So basically what I want to do is have the university LAN/internet running into the existing ethernet port on my Mac and then connect the ethernet port on the windows machine to the USB/Ethernet adapter plugged into one of the Mac's USB ports. The Windows machine does not have to have internet access. Is this possible? Will I be able to configure the two ethernet ports separately to operate two network connections? I understand the connections would require a different subnet mask and possibly a static IP for the computer-computer connection. That was a bit long-winded in the end.

Recently got a Mac pro. However my room only has one network socket going into my router, this goes to ethernet port 1. Internet works fine, no issues. However my old desktop (that the MP replaced) can't get online now - no second network port from the router into the room the computers are in. I have a crossover cable that I've used to connect the 2nd MP ethernet port to the PC ethernet port. However I can't get internet access on the PC. If the PC and port 2 are on their own subnet (not the router/port 1 subnet) I can get file sharing going between the MP & PC, but cannot figure out how to get the router/MP/PC on the same subnet together using both ethernet ports of the MP. I have already tried enabling internet sharing under system prefs etwork, but it doesnt work. Network: Router (connected to internet) at 192.168.1.1 - connected to mac MP port 1 - 192.168.1.2 - works fine in connecting to the net MP port 2 - 192.168.255.1 - works in networking to PC for filesharing PC - 192.168.255.2 - works in networking to Mac for filesharing Any combination of 192.168.1.xxx for the MP port 2 and PC, they can't fileshare anymore and there is still no internet for the PC. Anyone know how to do this?

I want to set up my dual gigabit ethernet as a network team; one for incoming traffic and one for outgoing traffic. (My machine acts as a server, with 2 internal raid striped 1 TB hard drives, and 2 external raid striped 1 TB hard drives (time machine for the computer); and 2 10,000 RPM raptor drives striped as my boot drive. Anyways, enough about that.) How do I do this? I currently have both ports connected to my Airport extreme wireless N with Gigabit, is there a way to do what I want to do with these products, or is there something else that I need to get as well?

i have a macbook and an airport express, which is plugged into a cable modem. i plan to buy a samsung blu-ray player (model 1600), which can plug into an ethernet port or, for more money, use wireless. i'd like to use an ethernet cable because I think the airport express gets overloaded sometimes (music stops if two computers using wireless, for example) and the wireless attachment for the blu-ray player is a little pricey. how do i create a second ethernet port? do i plug a router into my cable modem and then plug the airport express into one of the router's ethernet ports? if i do that, will it just work or is there some set-up work to do?

I've had the 13" aluminum macbook since October 2008 and I've never had a problem with the wireless or an Ethernet connection. I turned on my computer the other day and I couldn't connect to the internet through my ethernet port. I've determined it's not my connection (friend's macbook connects fine) and I've tried connecting to other ports around my campus and it still doesnt work. On network settings, the light is green, cable detected, assigned an ip address and dns but it simply times out when I try to connect to anything (firefox, itunes store, mail, etc.). I'm fairly new to mac os x.

I have added a new switch to my network and it seems that ethernet port 1 does not work on this new switch. My network consist of dhcp server>switch 1>switch 2. Switch 1 is in my entertainment center and had ethernet port 1 connected to this switch since I have had my computer but when plugged into switch 2 which I have just added to my workstation and on the switch there is no lights and in system preferences port 1 flashes between not connected and no ip address. For port 2 it connects fine and both ports are set for dhcp. I have tried different cables setting a static address and can not find a reason why it won't work.

What is the process used to direct certain IP addresses or a range of IP addresses to the second ethernet connection on a Mac Pro? I have a set of Mac Pros that use the first connection for internet access and corporate server connections using Samba. But the second ethernet connection is used for a lan between the Mac Pros and printers. It currently works but it take a bit for the "connect to servers" dialog to connect to a Mac Pro on the lan because I think it is searching Connection 1 first which has hundreds of Windows servers attached to it. And it takes several minutes to connect if our service has an interruption on Connection 1. All of the Mac Pros and printers are set up to use a manual IP address (192.168...) The Mac Pro workstations use Snow Leopard and we have a Mac Pro Server running Lion Server that we use to conntrol a network RAID.

My ethernet port is not working when cable is plugged in. Wireless works fine. Ethernet was working up until end of Feb. Then I turned it on and it wouldn't connect. Plugged into a friend's house still not working. Tried at work, still no luck. (I'm on a MacBook Pro late 2008)

I'm struggling to find the best approach here. Here's what I got:
1) Mac Mini 2.0Ghz running Snow Leopard
2) Mac Book Pro 2.53Ghz running Leopard
3) Mac Book 2.0Ghz running Leopard
My wife and I each use a laptop as our regular computer. The Mac Mini we just picked up and are looking to use it as a home server (although it doesn't have Snow Leopard Server). We use a program for our business called Daylite that hosts a database that we share between laptops - this is being hosted on the Mac Mini, which will always be powered on so we each can access it. There are also a couple folders that we would like to share on the Mac Mini. This Mac Mini will also sit next to our HDTV to be used for streaming, HULU Netflix, etc. My problem is that I don't know the best way to configure the Mac Mini on the network. I have a Verizon Actiontec Router and Comcast Internet (Dynamic IP, although it has been the same for some time). My questions are:
1) Does it make a difference if I have the Mac Mini directly plugged into the router via ethernet vs wireless? Right now, when we try and File Share between the Mac Mini and laptops, it takes forever to connect, navigate, save files, especially if I am saving to the Mac Mini, from a laptop using Photoshop or even Word.
2) Do I gain anything from running the cable modem directly to the Mac Mini and the enable Internet Sharing from the two laptops, as opposed to using the router?
3) I transferred 1 gig worth of files from a laptop to the Mac Mini and it literally took an hour. I retried it using a direct connection via eithernet between the two computers and it took 10 minutes. I'm hoping that optimizing my setup will speed up my local network transfers. Yes, no?
4) Can I used a Mini DVI to HDMI adapter from my Mac Mini to my tv? If so, does this also send audio signal? It's an Early 2009 Mac Mini.

I'm trying to connect an AE to my PC using XP with a D-Link DIR-655 WiFi router. I've used the airport utility and connected the AE to my router via ethernet. It appears to be setup properly and I can see it on the D-Link software. After disconnecting the ethernet cable and with the AE sitting next to the router it continually shows up and then disappears. The light is green on the AE. Then I disconnected the power and moved the AE into the place where I'm going to use it.
Now it will show up on my D-Link software occasionally but the light won't turn green. It also doesn't show up on the airport utility software. I also have a Touch and ATV that both work fine on the same network and the same location. The AE is about 30 feet from the router with only one wall in between them. Am I missing something here or could there be a problem with the AE?

I think this has been debated somewhere, but what's the best option? And what are the pros and cons of each setup? Actually I put my Netgear in "modem only" and setup the TC as the main router and configured PPPoE settings on it. Should I have chosen bridge mode instead?

I have a modem (Tilgin Vood 342) that came from the phone company which I use to connect my old desktop PC and my new MacBook Pro to the internet, through two separate ethernet cables. The modem has three ethernet ports and connects to the internet through an ethernet port in the wall. I want to buy an Airport Express in order to get wireless internet to my MacBook, but since my desktop PC can't receive wireless internet, I still need it to be plugged into the modem through a cable (I don't mind that). So my question is, can I use one of the modem ports for the Airport Express and another for the ethernet cable without there being a conflict?
I'm asking because I went to an electronics store and I was told that there might be a conflict and that I should buy an Airport Extreme or another router with ports in order for it to work. I would really prefer the Express because it's and it's the most I can pay for.
