Destination NAT on a Vwire?

L1 Bithead

Is there documentation on how to do this?  All I have found is incomplete.  Is the Destination Zone the same or different than the Source Zone?  Do the addresses have to include the subnet mask?  Are there any complete examples available?


Hello kentjday,

Just to let you know, the Virtual Wire NAT will only support IP address translation on an address which is not on the same subnet as the endpoint which is directly connected to our firewall.


My public address is x.x.106.137

My private address is

So if I understand your statement correctly I think they should work.

"No Active Sessions…"

There's your first problem. Doesn't look like the traffic is even hitting the VWIRE. In the 'show session all filter' command you used Pre-NAT IPs to filter correct?


Yes, and then I tried "show session all".  the same response.

ok nothing to do with NAT the V-wire is not working at all. I would start with checking the V-wire configuration and security policy.
