Destination NAT

‎09-12-2013 05:25 AM

Is it possible to implement destination address translation in the way when any destination addresses are translated into single address? And reverse packets should acquire the initial addresses as source IP.

Do you have examples for MX series and MS-DPC card?

There are teo features address-persistent and persistent-nat which provide the results, but these are defined for source nat. I do not know how if or how it could work with destination. What direction is your destination nat going to? outside of network or coming in from outside?

Ok. Sorry, but I do not have any experience with BRAS. If I could see the DNAT configuration and and an explanation of exactly what you want to achieve maybe I could help. But someone with knowledge and experience may contribute sooner or later. Either way, the feature is provided by using persistent nat or address persistent. Both will allow the external host to communicate with the internal host's original IP that it got. But you would have to be doing soure nat. Can you post your nat configuration.
