Multiple ethernet connections

Hey guys,
Is it possible to run 2 ethernet connections, potentially one for upstream and one for downstream using a standard ethernet port and a thunderbolt ethernet adapter?
Cheers
Jacob

I am not sure exactly what you mean by upstream,/downstream but yes it is possible to use two or more Ethernet interfaces on a Mac. Apart from the built-in Ethernet port, the second could be as you stated the Apple Thunderbolt to Ethernet adapter, or a USB to Ethernet adapter.
Possible usage scenarios include using one for the LAN and one for WAN connections, or bonding them together to make a 2Gbps combined link using 802.3ad aka. LACP trunk connection, or using one for the Mac, and the other for a virtual machine running on the Mac. Another common use would be to use one interface for the LAN to talk to computers, and the other for talking to a SAN via iSCSI, by keeping the iSCSI traffic on a separate interface you ensure it has dedicated bandwidth improving performance.

  • Multiple ethernet connections on a WDS with AirPort Express?

    Going through the AirPort Admin Utility and Airport Setup Assistant, and the various pdf manuals, the only way I can seem to create a WDS is for each device to be a wireless bridge.
    Even setting it up initially as a WDS that connects using AirPort (default config from the setup assistant), then changing it to connect via Ethernet completely broke the bridging and caused much mayhem.
    I'd prefer to set up the new Express device as a wired bridge, as I have a spare ethernet connection on the same subnet. I presume this would lessen the overhead needed by the WDS in general and would speed up the overall performance slightly.
    Does anybody have any clue how to go about this, if it is possible? I bet it's something small and stupid I've overlooked.
    Going back about ten pages in this forum didn't seem to cover this subject, so I apologize if I'm bringing up this subject AGAIN. Oh yeah, and all Airport Express devices involved are on firmware v6.3
      Mac OS X (10.4.8)  

    Disable the distribution of IP Address on the Express setup.
    You don't mention if you are using Airport Express or Extreme for your Main Base. If so then here is the link.
    http://docs.info.apple.com/article.html?artnum=107454
    If you are using a 3rd party Router as your Main Base then you will need to check out one of these 2 links and remember not all 3rd party routers are capable of WDS setup.

  • Does Airport Express support multiple ethernet connections via a switch?

    If I use the following configuration, with the Airport Express extending my network, will it handle multiple devices connected via a switch?
    Modem---Airport Extreme- - -802.11n- - -Airport Express---Switch---multiple devices (eg. network printer and iMac).
    Or do I need to use a second Airport Extreme instead?

    It works for me—even when the AirPort Express device is configured to extend the wireless network created by the AirPort Extreme router.

  • Multiple ethernet connections in one computer?

    I have two ethernet connections in my computer (2 IP Addr) I would like one connection to talk to a PLC(UPD) While the other (wireless) to talk to a printer across the room (TCP Visa Resource- open and write) Is this possible in LV7.1

    There should be no problem. Assuming your network is setup properly and
    each network card has its own subnet, the TCP/IP socket driver should
    route any package through the correct network interface.

  • Multiple Internet Connection Issues

    Hi there, long time reader first time poster.
    I figured I should post this as, while having read through hundreds of similar posts I still can't figure out how to solve my connectivity issues.
    I just bought a new iMac 21.5 inch 3.2Ghz i3 model and while I am happy with the machine overall, it is the second one in a month - the first had a faulty ethernet port and refused to connect to the internet out of the box. Apple replaced it without question - almost as if they knew.
    The replacement has now seemingly developed the same issue.
    Some background info. The computer was connected both through ethernet and through the TC I bought to back it up until yesterday. So I was getting both a wireless signal from the TC and one through ethernet.
    I have a hub that has 5 devices connected to it ( Printer, Cable TV, iMac and TC - now a PS3 ) That hub is served a signal by a simple NTT modem connected to a phone line. That modem is now nearly 5 years old but has always given great net speeds so I don't believe the problem to be the modem - I could be wrong though.
    I just bought a PS3 and tried connecting it yesterday but had multiple problems. Despite me entering the correct PPPoE information to the letter, the PS3 refused to connect, saying the password and username was incorrect. I could connect it via a Bluetooth signal but no hard wired connection would work.
    So I unplugged everything from the hub, shut down all the machines, turned off the modem and let it sit for 10 minutes and then plugged the ethernet cable from the PS3 straight into the modem, giving it a direct line. Switched on modem, rebooted PS3 and tried again - this time it connected through ethernet. I still don't know how or why. I can guess but I'm sure you guys know much more about this than I do.
    So then I tried connecting the iMac back to the net, reconnected all the hub, followed the same procedure. Off, sit for a bit, on etc. This time the PS3 has no connection and now the iMac has no connection either!
    The TC gave a green light though so I was able to get wireless. I tried removing all net locations from the iMac, installing new ones, renewed the DHCP lease, but no matter what I did (PPPoE info 100% correct) it just refused to establish a connection.
    The the bloody TC light flashed amber and I couldn't get wireless either despite being plugged into the hub and getting a signal! The PS3 is now working and the cable is fine so I am starting to think either I have cluster ****** the whole setup or something is wrong with the iMac.
    I go away for an hour then come back and the stupid TC has somehow picked up a connection! The light is green again?! But now the time connected display is scrolling repeatedly. I've got net but what the **** is wrong with all this?
    Bottom line - not ethernet connection for the iMac but TC seems to be working and all other devices have a connection.
    Please help me if you can! I just can't figure any of this out.

    Your description is a bit confusing, but I use English as a second language, so it may be just me.
    1. How is the hub connecting to your modem, by ethernet cable or wirelessly?
    2. Which device is negotiating the internet connection with your ISP, the modem?
    3. Does the device that negotiates the connection use PPPoE?
    4. How are the other devices being handed their internet connection? DHCP only?
    Only one device should be connecting directly to your ISP using the PPPoE protocol and configured with your account username and password. This device is preferably the modem. This device should be configured to hand out internal IP addresses to the other devices on your LAN using DHCP. All of the other devices should be configured to request an IP from that device, whether by ethernet or wi-fi, just with DHCP.

  • Ethernet connectability completely frozen-out by frozen SES-mode; WTR54GS

    On a reset i accidentilly hit the SES button, now on my ethernet connection, the "Secure Easy Setup" button is frozen white. i've browsed th web, found other people have encountered same problem.
    i've spent probably 100 hours, trying many fixes, including your company's suggestions -- to no avail! (note: multiple reset attempts still won't fix this).
    my PC and ethernet card work fine on other products, it's just that wtr54gs has now frozen me out by your proprietary SES-mode. i've tried, via the wireless set-up, assigning fixed ip ( e.g. : 192.168.16.100) to my ethernet + your suggsted 192.168.16.50 to re-flash firmware -- nothing works! can't even get a dhcp ip from wtr54gs,because the frozen SES-mode has my ethernet connectability completely frozen-out.
    re-flash firmware won't go on wirelessly either, a "failure" message appears like "not suficient system resources" -- **bleep**! -- on my Windows task manager networking screen i see i'm sending megabits of
    firmware data, but the wtr54gs only picks up about 10% of the sent amount -- seems the wtr54gs can't handle the speed my wireless adapter is sending it ( also connection is strong, i'm 4 feet away from it ). i don't know how to force data rate to go slower ( on ethernet card i've reduced rate + to half-duplex, but, of course that a no go, since the wtr completely has my ethernet connection frozen-out in the first place, my original concern!).
    i bought a D-link DWL-G730AP travel router, hoping theirs would be better, but it's very shoddy, very poor reception and difficult interface. i'm returning that. i long for the days when my Linksys product used
    to work -- Please Help Me Fix It !!!
    i used to use wtr54gs as a client-mode, connected to my PC via the ethernet connection, and the wtr54gs incoming internet connection was set to "wireless" -- all woked great, until this freezing-out problem.
    if the SES-mode is internally permanently freezing me out on ethernet connectability, it appears i'm going to have to get a replacement ( as, other people on the web, similarly-situated, have stated).
    my original purchase was about $60, but i see Amazon is recently selling the wtr54gs for $180!! -- i'm NOT buying a replacement at that cost!! please, either help me fix my frozen wtr54gs, or, since i'm

  • Can MBP run both WiFi and Ethernet connections at same time?

    I've been running my mid-2012 MBP via USB and WiFi. 
    I acquired 8-port 10/100Mbp Switch.  Can I run hardware like printers, external HD from MBP via the Ethernet switch and still keep USB connections and WiFi net for other purposes at same time? 
    (I found USB-ethernet adapters on internet)

    Macs and many PCs can keep multiple network connections going. When you look at the list of connections in the Network system preference, the one on top is the primary connection and if you want another network interface to be the primary (like Ethernet) you use Set Service Order to drag it to the top of the list.
    But when you do that, I think all services use whatever is primary. What I don't know how to do is make specific applications use specific network interfaces.

  • 2 x ethernet connections

    I have just installed another ethernet card into our G5 PowerMac server which is running OSX Server 10.4 (all software updates have been installed) ... The current setup essentially boils down to:
    en0 - has an external IP address that has been statically assigned by our router
    en1 - has an internal IP address that has been statically assigned by our router
    The problem is however, when there are two ethernet connections, our server freezes (the only way to get it out of it, is to hard restart it)...
    Does anyone have any ideas of how to resolve this issue?
    Thanks,
    Elliot

    Does anyone have any ideas of how to resolve this issue?
    Not without more information.
    Every single one of my servers runs with multiple (usually 3) interfaces, so it's not a fault of Mac OS X Server, per se.
    Therefore the problem has to lie in the configuration.
    When you say the server freezes, do you mean it no longer accepts network connections? or are you on the console (e.g. using a monitor and keyboard) and it freezes there, too?
    What do the logs say? especially /var/log/system.log
    If I had to hazard a guess I'd say your internal network has a higher priority and it has a router address defined (typical if you're using DHCP). Your internal network should not have any router address set (you're not routing over your local network) so the proper solution would be to change that to a static address (servers, generally, should be statically assigned, not using DHCP, although there are exceptions).
    In the mean time you can reorder the network interfaces in System Preferences -> Network so that the external interface is listed first.

  • Cisco 3750x no ethernet connection

    Hi,
    I seems to have a weird problem whereby clients are unable to get an ethernet connection (Port no LED lit/not connected) when using mac.  Sometimes there is connection after multiple insert/disconnect using the same cable to the Mac client. This has also be tested with a direct connection between the client and switch (without going thru the backbone cabling). If I was to try using Windows client, there does not seems to have such issue.
    Further observation; from the switch; if a shut and no shut was performed on the port connected to the client, it would cause the connection to be "UP". Not too sure if anyone may have seen similar issues of unable to get connection "UP"? The firmware on the switch is running 15.2(1)E2.
    Any suggestion is appreciated.

    You've got a 3750X?  Good.  This means you can test the cable run using TDR.  

  • Apple tv ethernet connection not working

    Connected my new Apple TV to the ethernet cable and it doesn´t show the network available to connect to internet.
    Am I missing some step ?
    Thanks

    ISSUE
    After the latest software update, my Apple TV2 has stopped recognizing any form of network connectivity and appears to believe that it's connected to the network via an ethernet connection, whether or not there is one actually plugged into the back of the device.
    BACKGROUND
    I echo many of the previous posts... I've had Apple TV2 for over a year with no difficulties. Ethernet and wireless connections have always worked. For the last 6 months the Apple TV2 has been hardwired via my ethernet connection with stellar results. However, after the recent software upgrade, I've lost all network connectivity. Apple TV2 will no longer recognize the same ethernet connection it's always been attached to.  This is the same connection that has always allowed me to watch iTune movies, Netflix and download/install all previous software updates. Worse yet, when the ethernet connection is unplugged from the back of the device, Apple TV2 believes it is still connected to the ethernet cord, as if it's stuck, and WiFi functionality does not kick in.
    TROUBLESHOOTING
    This specific issue has nothing to do with the actual "network" so I am kindly asking people to stop recommending that we check our network/router settings and ethernet cords. Apple TV2 is designed to automatically activate its wireless function when an ethernet connection is not recognized. It's should be pretty obvious to anyone who is tech savvy that there is something wrong with the device and not the network, with respect to the specific aforementioned symptoms.
        STEPS
    Nothing has changed on the network and I've tested the ethernet connection with both MacBook Pros... with success.
    Restarted device multiple times
    Attempted to restore device but no network connectivity makes this impossible
    Connected device to iMac via micro USB cord and restored from scratch
    Made the assumption the wireless antenna could not recognize network due to location, surroundings (i.e. tv stand, Directv receiver, SP3), etc. Moved Apple TV2 to another location and connected to different TV. Wireless functionality still does not activate when ethernet cable not plugged in.
    All other common sense troubleshooting steps have been taken per Apple's troubleshooting recommendations and other blog site recommendations
    I'm sure the latest software update worked for the majority of all Apple TV2 owners. Anything could have gone arwy during the update that could have caused this specific issue to present itself.  Either way, there are enough folks with the same complaint to warrant a deeper dive of the issue.  My next step will be to jailbreak the device since I have nothing to lose at this stage... it's a simple paperweight until I find a solution.

  • Multiple ethernet addresses vs. IP addresses

    Hi,
    Using Workgroup Manager on SLS 10.6.4, I have successfully mapped hosts and their MAC addresses to fixed IP addresses within our LAN. All is well, until someone works on the back of one of the Mac Pros and ends up plugging the ethernet cable into jack #2 instead of #1. Now the MAC address is unintentionally different.
    I suppose I could make a secondary set of hostnames for ethernet2, but that seems ugly and if you're depending on host foobar being available for a particular printer, but it's now foobar2, that seems unpredictable.
    How do you deal with this? I assume this is in the same realm as having a laptop that connects via wireless one day but via an ethernet cable the next day? It's the same host, just not the same MAC address. Does WGM have a way to deal with multiple ethernet addresses?
    Thanks,
    -- Antoine

    ahh, i see.
    you're running up against a few limitations here.
    bootpd uses MACs to define static mappings.
    OD uses MACs to identify nodes/clients.
    your client machines have multiple MACs and may present one or the other on the network, depending on whether someone plugs in the wrong port.
    here are some options/workarounds off the top of my head:
    1. disable the second interface. if you need it for some reason, you'll have to deal with this situation another way.
    2. bond the two interfaces. the downside is that you'll need to have both plugged in for optimal results, but you'll have one MAC, i believe.
    3. use another dhcp server configured to deny all dhcp requests except those from your approved MACs (en1, let's say).
    4. use local MCX and not deal with changing MACs at all. this is a little more difficult to manage, however.
    5. manage prefs in some other way, like with puppet or casper, that don't strictly depend on MACs.
    i'm sure there are other ways to deal with this situation, but if you're managing these systems, i'd probably just disable the second interfaces. people will learn quickly when they can't access the network. determine if this is more of a technological or a policy/personnel management issue.

  • Lightening strike killed Ethernet connection and more?

    Lightening killed my ethernet connection. I saw a post that said a 3rd party replacement board would do. I installed it (Sonnet's Presto Gigabit 10/100/1000 PCI) and I still don't have a connection. Internet provider's modem talks and my Mac 10.4.2 sees the new board but no connection. Reloaded OS to not avail. Everything else works fine. Any advice?

    I too read the various reports on xlr8yourmac about the NetGear GA311. My husband had purchased this card to try in my son's PC that had lost its NIC card in the lightning storm as well. It didn't solve the problem on that machine. I found another post on Amazon by a reviewer who said he is an Apple Certified System Administrator. His report was that the GA311 should work in Tiger 10.4 and later without a driver.
    I've now tried the card in my G4 Sawtooth, similarly impaired by the storm, and after multiple, varied attempts to set it up with the Network preferences am unsuccessful. Network preferences recognized that the device was in the PCI slot and attempted to set it up. It just can't seem to complete the task.
    Now I'm wondering if there may be some other related damage on the machine that would affect its ability to connect to the Internet. Does anyone have any ideas about that? What other components are part of that capability on the G4? Can I try replacing an additional component while also replacing the card?
    Thanks for reading this post and sharing your feedback! I really want to get my wonderful G4 fully operational again. I have my new MacPro up and running now and its wonderful, but it won't run the majority of my Classic compatible software, like QuarkXpress 5, Flash 5, etc. I would like to continue having access to those programs.

  • Ethernet connectivity issues

    Hi
    We've just setup our hi-speed internet and plugged in my one laptop, it worked flawlessly immediately.
    When we took the same ethernet connection to another Powerbook, both with OS 10.4.8, it didn't pick it up. On the laptop that doesn't work the ethernet connection is not being recognized, the one that works has an address.
    The connection that doesn't work is on a latop that was configured to work with the wireless connection at work, not sure if that makes a difference.
    I'd really appreciate some help with this as we're new here and need the internet for setting things up.
    Thanks in advance
    Any ideas as to how I can solve this?

    What kind of high-speed connection?
    If it's cable, the cable companies, for some unknown reason, continue to lock their boxes to the first device they see. This means that if your MacBook is the first device the cable modem sees, then that's the ONLY thing it will see until it's power-cycled. It's a ridiculous situation, with an annoying workaround.
    (The other solution, of course, is to get a NAT router of some sort... it talks to the cable modem and shares the connection amongst multiple other machines behind it, which the cable modem never sees directly).

  • Multiple ethernet network adaptors + MySQL/php5: configuration help needed

    I would be grateful if someone could give me some advice on how to configure multiple ethernet adapters under OS X 10.5.6
    I have set up my system to work nicely with two ethernet network adapters, each with its own fixed IP. This bit works just fine. The machine supports two separate servers - a mail server and the OS X Apache2 server. I have configured the mail server to only listen to one of the IPs, and the Apache2 server to listen to the other (via httpd.conf). The system also has MySQL and php5 installed / enabled, and these services are only used by the Apache2 server.
    The problem I have is that when I start the machine, initially the php5 system cannot connect reliably to the MySQL database system. The fix I have found is to temporarily make the ethernet adapter connected to the mail server 'inactive'. While this is so, the php5/MySQL connection to Apache2 works. Curiously, once an initial connection between php5 and MySQL has been made, subsequently I can make the mail server's ethernet adapter active again without further problems.
    I initially thought this might be due to 'service order' issues - but changing the service order (e.g. putting the Apache adapter 'above' the mail adapter in the service order does not help. The fix only works by making the mail adapter inactive temporarily.
    I suspect that there is some configuration change I can make to clarify the setup I have. The MySQL and Apache installations only need to talk to the Apache server - but I am not sure how to record this configuration in the OS X system.
    Thanks in advance for any assistance that you can provide.
