Need advice on a internet/gateway/firewall set-up

[Thomas Fischer <tvfischer.l@xxxxxxxxx>]

Hey all,

I need some advise on the best type of set-up under Fedora including 
configuration examples to build a «dual-homing» gateway/firewall.

The idea is to have the following set-up

   internet_ip_1                  internet_ip_2
         |                                       |
         |                                       |
         ------fedora_gateway-----
                        |
                  internal_network

So that is the network configuration, which will be put into place using 
3 physical ethernet cards. I am thinking of bonding the 2 internet 
facing ethernet cards but not sure how that would work with the 2 
internet ip addresses.

Any suggestions? How would I load balance the access across both networks?

Thanks for the help
