    I just got myself a NAS and I'm trying to figure out how to setup windows 10 so that:

    1. the 1st NIC is used if I want to access the internet and,
    2. the 2nd NIC is used if I access the NAS.

    I have both PC NIC's and both NAS NIC's connected to my router.

    looking for a bit of a "Dummies guide to" to get this sorted.

    I basically don't want my internet to slow down if I'm transferring files to/from NAS at the same time if that makes sense

    I have this setup at my place, 2 nics per computer, first one just uses tcip v4 only (everything else unchecked) just to browse internet, second nic has a fixed ip like 192.168.2.55 / 255.255.255.0 for local networking and NAS access.

    To avoid having issues accesing other computers edit your hosts file to reflect the computer names and ips, example:
    192.168.2.55 computer1
    192.168.2.56 computer2

    hmmmm

    Code:
          /NIC#1===========|           |==========NIC#1\
         /                 |           |                \
    PC                     |  Router   |                     NAS Box
         \                 |           |                /
          \NIC#2===========|           |==========NIC#2/
    this is my crude representation of my setup. Both NIC's in my PC go to the same router as do both NIC's in the NAS.

    everything is on the same SUBNET. can I still do it or do I have to have my 2nd NIC bypass the router

    I'd leave the nas out of the internet for security reasons.

    Have NAS on a different subnet. Make a route to it from your PC second card (that is on same subnet as NAS)
    But your reasoning makes no sense. Your NAS is not on the internet, it is on local LAN, if you do not do any NATing on the router, it stays so! Also if you worried about ie viruses etc, the worry about your PC, and not NAS, as it is your PC that has (whichever way) direct access to it!

    Probably not possible on the same router, you should just use a crossover cable:

    Code:
          /NIC#1===========|           |========== Interwebs
         /                 |  Router   |               \
    PC                                      
         \                
          \NIC#2===========================NAS Box/
