I have both a dynamic cable wan connection and a pppoe dynamic dsl wan connection. I have the RB600 series router with L4 version of recent routeros. I figured out how to make a single ip inside the private network be nat'd to use a single interface and have port forwarding to that device. What I want to do now is have port forwarding setup on the pppoe interface to an internal ip (my gaming pc) but use the other wan connetion for everything else from that internal ip. I setup dst nat rules and a single guest can connect through the port forwards.. but after the first one no more can connect. It works fine if I do the setup with a single wan connection with normal routing and firewall rules. Any ideas on how to get this working with dual wan setup or need more info, please reply.

Thank you.
