I have Clark Connect for a gateway running Red Hat 7 with 1 client PC hooked to the gateway. Whenever I am having some network troubles, the first step that I take is restarting the network service which included eth0 and eth1. I go to /etc/rc.d/init.d and restart the network service by typing ./network restart. It apparently restarts OK, but when it comes back up, the client PC does not route past the gateway. I have noticed when it is shutting down, it says "Disabling IPv4 packet forwarding", but does not show that it enabled it back. I THINK that this may be the problem. To get things back online, I have to reboot the gateway. Does anyone know what would cause this?
Edit: Whenever the network service comes back up, I can ping out from the gateway and also ping the client. The client can also ping the gateway, but not get past it.
