I have this one server that just doesn't want to be on the internet

It's a new server, a twinblade, the other twin works, but not this one.

It can connect fine to everythign else in the LAN, but cannot go out on the net

It can be reached by ICMP requests over the net (the nagios server can probe it, but not ping it for instance), but not TCP

Everything seems fine both in firewall and machine, i get no issues.

Anyone care to help me out where i can start looking, i'm seriously confused.

edit: it can ping gateway and through the sonicwall site to site VPN, it\s also able to resolve DNS. the only thing it can`t do is reach anything outside of LAN/VPN
