OK, I have been struggling with this for weeks now. I have an XP box working just fine, right next to it is my more powerful FC3 box that refuses to work. It says it can't connect to the internet when I try to attached to projects. If I turn off iptables (/etc/init.d/iptables stop), it still fails. I can browse the web/do anything I want on the internet with no trouble. On my XP box, tracert setiweb.ssl.berkeley.edu works just fine, on my FC3 box, it stalls out (astericks) at the final step (right after g6-1.inr-230-spr.berkeley.edu)??? When I use Ethereal to monitor packets, I have noticed that the checksum seems to fail on the outgoing packets to test for connectivity under FC3, never tried under XP since it has been working. Does anyone have any clues? It must not be my firewall since stopping iptables doesn't help (good reasoning there or false logic?), and I can't understand why the server will respond to a tracert from XP but not a traceroute from FC3 (they should both simply be sending ping requests, right?). Needless to say, I would like to get this machine back up and running since it is now sitting idle, does anyone have any suggestions? My FC4 install at home over a modem worked with no troubles, so I am completely stumped.
