Newbie question - IP routing through a firewall

["Asier Azaceta" <azaceta () comunet es>]

Hello,
this is the first time I write to this list. I know this question may look
pretty stupid, but I won't be rest in peace until I know the right answer.

I've got a network structure similar to this:

       Internet --- Router --- Firewall ---- Internal Network
                                  |
                                  |
                                  |
                             Server Farm

Right now, I have no direct control over the router, that's way I want be
sure before asking for any setup modifications on it.

I've read you shouldn't have IP Routing enabled in the firewall, that's
fine, but my question is: Should the router pass all the traffic to the
firewall? I mean, should it have a route like 'internal-network gw
firewall'?

I've tried to find the answer in books, but every one obvious this subject.
Can you help me?

Thanks in advance,
