Here is my situation:

LINUX Server (eth1) -- SWITCH
Entire Network

Internal network is withing the range.
Linux server is running a home brew firewall script with IPTABLES
Internet is connected via cable modem @ eth0 interface
Internal network is connected @ eth1 ( interface

Here is my routing table (autogenerated):
Destination Gateway Genmask Flags Metric Ref Use Iface * U 0 0 0 eth0 * U 0 0 0 eth1 * U 0 0 0 eth1
default d54c22001.acces UG 0 0 0 eth0

Each device on my internal network has no problems at all with internet connection. But on my linux box itself I cant get it to work. No ping, no www, no ftp ..... (dns works fine cause gets resolved via my internal dns server)

Something wrong with routing table ?
