Firewall problem: Only works on a restart.

[postmaster]

Check /proc/sys/net/ipv4/ip_forward. before restarting fiaif. It should have a value of 1. 
(Or do a /etc/init.d/fiaif test- If forwarding is disabled, it will be noted as an error).

Fiaif sets this if it sees that it is not set, so my guess is that Fedora 10 sets it back to 0 after the firewall has been started. 

Restarting the firewall of course fixes the problem.
