For the last few years I've used a FreeBSD box as my house net gateway. It has two NICs. The inside NIC has access to the Class-C house network and a DSL router (no firewall). The outside NIC is attached to a cable modem and uses a static IP from the cable company.
Using the ipfw tool, I've added a rule that says that anything from the inside net that is destined for port 80 or 443 (http and https) shall be forwarded to the NAT daemon and from there routed out the cable modem. This moves most of the household traffic off the DSL and onto the Cable modem. I'm attempting to figure out how to do the same thing with Vyatta. The goal is to have two inside nets. 192.1.1.0/25 with vyatta as the router at 192.1.1.3 which then forwards firewall approved traffic to 192.1.1.1, the DSL router. This is for my DMZ machines. The second inside net would be 192.1.1.128/25 with vyatta as the router at 192.1.1.129. Here any traffic with destined for port 80 or 443 will be NATted and sent out the cable modem and all other traffic sent to 192.1.1.1, with firewall approval. Any suggestions or pointers will be appreciated Thank you, Chris Johnson PS I'm testing VC4 right now but if somebody can show me how VC3 is fine. Just trying to avoid an upgrade in the near future..
