I have a cablemodem, and a network with several computers on it. The firewall (Astaro) can ping and resolve names on the internet, internal machines can ping the firewall, and the firewall can ping internal machines. But when I try to ping an address, it says "network is unreachable". Name lookup returns nothing.
I am not entirely new to this. Routing table looks right, I have masquerading set up in what appears to be proper format, and just until I can get things working, I set the packet filter to allow any traffic.
I have seen that this topic is not new, and that others have had similar troubles. But none of the previous solutions have helped yet. If anyone has any ideas, I would greatly appreciate your help.
