I have read some games for some reason do not like using 2 nics in that kind of setup.
I notice when I remove the router (Nexland pro 800) it seems a bit faster on response times overall (surfing/gaming) to me so how much more efficient can it be under a full load of clients on a game? (router vers straight shot)
All this machine is for is hosting games anyway.
I really do not need a firewall if somebody wants to hack my game server go for it
