Standard IP routing, the default gateway of the network can decide based on a route entry whether to send it to the cable modem or send it to the firewall.If the source block is not routed via both connections it won't work without NAT. I had this same problem trying to use my ISP's native v6 over PPPoE and maintain a tunnel as backup since it was still pretty flaky as they were testing it at the time ... no way a residential ISP is going to route 3rd party blocks for all their customers, and no chance the tunnel provider was going to route the block my ISP assigned me either ... with no NAT66 in Tomato/ddWRT/etc it was 100% impossible to have multiple connections ...
I guess I'm a little confused on the setup. You have a firewall with a connection to a local LAN, another connection to customer network(s), and a third connection to the Internet via cable modem? You have NAT setup to NAT your Local LAN out to the Internet and to the customer network? A customer network device would use the outside IP on the customer network connection to communicate with devices in the Local LAN? I think it makes more sense to me now. -- Matt Reath CCIE #27316 (SP) matt () mattreath com | http://mattreath.com Twitter: http://twitter.com/mpreath
