| Setting up a Linux Home Gateway | ||

First ping your gateway system from one of your workstations. Then access a web site or an external system from your gateway and finally try to connect from your workstation directly.
If you can't go beyond your gateway, try printing your rules using "iptables -L" or "ipchains -L". See if they are okay as per the instructions. Check for other system settings and see if all the network interfaces are up in your workstations and look into their configurations. To view the established connections, do
bash# cat /proc/net/ip_conntrack |
Some of the troubleshooting tips include checking for the ifconfig output on the home gateway. You should also see a loopback interface other than the ppp0-eth0/eth0-eth1. Check if network hub is powered-on and all the relevant lights are on in the network hub.
If you can ping the gateway's external IP address but not he hosts on internet, make sure you are not running 'gated' on your gateway.
