Hi Haiyan, Can you please be more specific. For example what other traffic except from interface A and B will be passing (are there other interfaces involved) ? Using nat44-ed forwarding is a bit tricky. It let's pass traffic without translation if a preexisting session isn't found so this would mean only static mapping get's translated. Forwarding feature is used for specific purposes when in mixed environments you have A configured as inside and also outside and B configured as inside and outside also.
