[Sheflug] Re: Firewall

I don't understand what you're talking about at all. I've never done 
networking before. What is a gateway? I only have two machines, this one and 
the firewall. It says in the docs to use the IP 192.168.0.1 and doesn't 
mention anything about another port when connecting through the browser.

Another exception for you: classless subnets. Unless you're using a true 
point-to-point link, which would be a /31 subnet, every other classless 
subnet has a broadcast and network address, a la:

	192.168.0.128/30
gives broadcast 192.168.0.132, network 192.168.0.128. I think. Classless 
bigger than /25 also gives you some funny math when working out the 
broadcast/network, it's not necessarily straightforward.

Cheers,

Alex.
