eth0 info is set up correctly, i can ping out, surf the web, access my files on my windows boxes from samba, etc. but when i go to transfer a large amount of data to my server after about 8minutes or so it 'craps' otu saying <windows side> 'network source/device is unreachable' or something to that effect. I have iptables trained to only allow connections to my internal network x.x.0.0/16 .. i even <gasp> took the firewall down to make sure it wasnt messing anything up. SElinux is disabled, etc ... even replaced the NIC last night with a new gig netgear card. mac addre updated and cruising the web,etc works fine until i go to do the mass file transfer... any thoughts ?
