Hello Community,Recently I faced interesting behavior of Cisco's routers and switches. I was playing with NAT configuration and just accidently observed situation when ping reply was with the different source IP address than the destination IP of pin...

@Richard Burts Hello. Thank you for the reply.1. I already tested scenario you provided and in that case R2 will reply to R1 with ping with source 172.16.2.2, not with address of outbound interface. Even more, you can ping loopback interface of R2 a...
