Hi,
My Problem is:
If I initiate traffic for both outside NAT interface (G0/1 and G0/2) from NAT inside interface G0/0 the NAT translation table for both interfaces will be established but only from outside interface G0/1 targets got responses. If I remove the configuration for interface G0/1, I got answers from targets at G0/2.
The problem results from subneting/overlapping of the address spaces of g0/1 and G0/2.
If I use two class C network masks for G0/1 and G0/2 it all works fine. Because I can't change the address space, my question is: Is there any possibility to configure a functionable NAT-configuration by keep the address overlapping for G0/1 and G0/2.
