My topology is as in the attachment. I cannot understand what I am doing wrong. I am wanting the network to be setup to where my 2 machines (that are wired to the router, and multihomed, the second port with a 1gb NIC using crossover to each machine for file transfers. Any time I have it set up, it either refuses to connect to the internet (using various commands I found that it is because I had a default gateway set to the 1gb NIC with the crossover, and it was choosing to use it for internet access) or the two machines refuse to even ping one another (without a gateway). I've tried under different subnets (eg, 192.168.10.1/2 with subnet 255.255.255.0 and I've tried 10.18.1.1/2 with subnet 255.0.0.0) and neither work, bot have the same problems. I have Homegroups disabled, file and print sharing set with accounts. Windows 7 Professional on each machine, Linksys BEFVP41 router. What am I missing?? Thanks for reading.
