Cisco 837 / iOS 12.4 / How to do Source and Destination NAT at the same time?
I have 2 ADSL Lines connected with two Cisco 837 Routers, and I need incoming port-forwarding. But it seems that I am unable to configure the router to do not only incoming destination NAT but at the same time also Source NAT so that the outgoing packages will be sent to the same router where the incoming connection originates from and not to the router defined by the current default gateway.
I also can not depend on an IP (dynamic IP's) so I would need a solution which uses the interface (dialer) instead of an configured IP.
