F8 as Router is not working any more!!!



I had to re-install F8 as upgrading from DVD failed on dependency
check (freezing)
My router was working fine in F7, and it was acting as a router with
transparent proxy
I had backuped all etc configuration files, so I copied back iptables,
squid.conf, systcl and rebooted.

Some notes:

eth0 became eth1 during installation
eth1 became eth0

I set back each card as in F7 (eth0 is the card connected to the
Internet, eth1 to my internal network

I can ping eth1 but not eth0 (that I should get as it is acting as a router...)

This is my iptables
