      you need to explain the problem. What you are trying to achieve, what rules you put in the routing ruleset, and what happens.

      Today i have 1 server CentOS 5.2 with IPTables 1.3.5 and FWBuilder 3.0.4, in this server i have 2 internet links, 1 DMZ and 1 internal network.

      - the first link I would use all the traffic services (pop, smtp, http, dns, and other services).
      - the second link I would use to access from internal network to Internet.
      - I have in DMZ network only pop3, smtp, and webmail.
      - on the internal network I have some public services, which must pass through the first link.

      below an outline of the network: (is better in text mode, )

          |D |eht2(10.1.1.x)
          | M| only 1 server in this network
