Does your ipchains/ip_tables rules block ICMP (eg ping) requests? If
so then, try stopping them. You should be able to ping your default gateway. 

What does ifconfig -a report? Are your interfaces up? working? 

ipchains and ip_tables are basically the same. ip_tables is newer and probable
the preferred choice.
