Hi Team,
I have this server with ip 10.4.1.122 and trying to reach other end server 10.4.7.100 (192.168.31.3). once it reach the router we have done a source and destination nat. So 10.4.1.122 become 10.20.30.21 and Destination become 10.4.7.100 to 192.168.31.3.
Good thing other end device receive the ICMP, but we did not get any reply. so we capture traffic on router and realize when we do the ICMP ping from our server to other end nat works fine and it reach the device. but when the reply return to router, nothing happens. So do i need a reverse nat and if yes how to do so?
because what i see from packet capture is on GIE 0/0/0 incoming traffic is there but no outgoing. probable due to reverse nat not there.
I draw a simple diagram with what command i used. appreciate ur expertise.
