I have a Bordermanager 3.5 server which I am working on setting up the IP
Filtering rules to allow only what I want in and out. The server has a lot
of Route Statements in the TCP/IP Static Routes table. Does the routing
take place before or after the firewall filters? Do I need to set up
explicit rules in my filtering rules to allow packets to traverse those
routes. If so, how should the rules be constructed?

I can provide more details about my routing table if neccessary.
