Using 2 nics on server on one network, how do I do it? RRS feed

  • Question

  • Ok, i'll preface by stating that I know that nic teaming/bridging isn't officially supported in whs.  But here is my predicament.  I have installed a ceton pci tuner card into my whs2011 server.  In order to get this to work so I can stream to my htpc and another computer, you need to bridge the ceton tuner to your nic.  I have done this with easily with only one problem.  For some reason the bridge, while allowing my to stream my tv, severly limits my other network transfers.  Where before I was always able to transfer large, compressed files around 110 MB/s, I can now only get max 50 MB/s up or down.

    Before I was just using the onboard gigaNic adapter, and got max speed.  Then after bridging with the ceton and seeing the slower speeds, i thought the onboard nic just couldn't handle it.  So I bought another Intel nic, so now all computer have the same nic on my network.  This resulted in a slight increase in speed (10%) but something is still not right.

    So what I would like to do is just have the bridge carry the tv stream, and use the other nic for other network tasks (file sharing, remote desktop).  Can anyone give me some advice?  At first I thought it would be easy enough, but i now realize I have no idea how to configure the nics for each type of traffic.  I was able to get speeds up quite a bit for a while, but it was a fluke or something because I can't seem to replicate the settings.  Then when it was working, I couldn't remote into the server.

    So, to summarize, I would like:

    1 nic that is bridged to the ceton tuner to only carry tv stream

    2 nic, intel gigabit, to do everything else

    I am using an e3000 router and a dlink 5 port switch

    Thanks for any help!

  • What you want to do is route packets on certain TCP/IP ports to one NIC, and all other packets to the other. Unfortunately, in order to do what you want, I believe you need what's called "policy based routing", which isn't supported on Windows OSes.

    My recommendation would be to put the tuner card into a dedicated PC.

  • Thanks for the reply.  I could put it in the htpc, which I have had it in before.  But i have reasons I want it in the server.  It's actually more reliable there.  I have no issues with the card not being available, as the server is on 24/7.  And a bonus of having it in the server, is that I can tune channels almost immediatly when I resume my htpc from sleep.  Whereas if I had it in the htpc, it takes 1 to 2 minutes to initialize.  So now my htpc is functioning more like a cablebox, which the wife likes.

    And it seems there are network policies that I can define through the network policy server (NPS), but I don't have the foggiest how to do so.

  • NPS is used for RADIUS authentication; it's not likely to do what you want. But you can learn more about it here.
