2019-01-16NAT: Fixed issues with dropping reverse packets with output-feature.Dmitry Vakhrushev1-0/+32
Fixed NAT issues with dropping reverse packets in case NAT worked in 'endpoint-dependent' mode and outside interface has FIB different from 0 when the output-feature is set. In this case, the out2in_ed dynamic hash key was not being created correctly. Change-Id: I6362967f4b09a375a4606eedaa8e264795b25453 Signed-off-by: Dmitry Vakhrushev <dmitry@netgate.com>
