Hello
I have a problem trying to make my linux box route packets. It's a Fedora Core 6 x64. The box has two network interfaces + a PPP interface. I tried routing packets from my LAN to PPP and also from my PPP to LAN, but it doesn't do it. I thought to see why, so the ideea would be to log the packets that get dropped, but I can't manage to do that. If you can help me I would be really gratefull.
Here's my /etc/sysconfig/iptables:
# Firewall configuration written by system-config-securitylevel
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
