smoothwall

Hi,

I'm having problems with the configuration of SmoothWall. It's a really annoying case.

I am the system administrator of a university network. I've been working here for hardly 5 months and when I arrived here there was (and actually still IS) a computer dedicated entirely to the function of "smoothwalling" (that means DCHPing, firewalling and intrusion detecting); but the computer has two bad points:
  1. It is a really old one nowadays
  2. Its DHCP is configured to give class C addresses and now we have more computers than class C addresses can supply.
So we have decided to buy a brand new one and I am the person in charge of configuring the last version os Smoothwall on it. I have installed it with the following configuration:
- GREEN (172.16.1.1) + RED (212.164.34.200)
I have assigned the 172.16.1.2 address to a computer connected to the GREEN network and I am able to ping from it to the new firewall (not to the old one nor to any of the other network computers, as they have class C addresses instead of B).Now, the problem comes when I try to ping to the outside of the network. This is the situation:
1. The network cables are OK and properly connected to the right network plugs and network adapters.
2. The RED NIC address is a valid one.
3. When I ping to the router of our service provider we have direct access to, the ping works fine, but I cannot ping to any other external address, for example, to the www.google.com address (212.239.57.100); it says:
  "Reply from 172.16.1.1: Destination host unreachable."

Can anyone help me with this (surely STUPID) problem?
Do you need more information about the actual configuration? Ask me and I will tell as soon as possible.

The default gateway was misstyped. I was right when I said it was a STUPID problem.
