My dsl provider has my house on several subnets (ips obtained via dhcp, along with a netmask of 255.255.255.0), so I have had to screw around with each machine to make sure local traffic doesn't flood the dsl modem. To remedy this, I've been trying to set up a firewall box to basically reroute those three subnets as local, but I'm finding it very difficult. It seems like every doc out there only addresses nat, which is definitely not what we want. I'd greatly appreciate some help accomplishing this.
Thanks much, William
