Can't get 1:1 working properly
-
Hello. My first post here but have been using pfsense for a few years. Rebuilding a firewall from scratch. Wanted to start clean so that is why i did not restore the config.
I have googled the you know what out of this question before I posted. Here it goes…
I can't get 1:1 nat working. Anything that I 1:1 stops functioning. As soon as I remove the mapping it works again but is nat'd to the wan address.
This is running in an enterprise network with many subnets. I am attaching a simple network diagram and a screen cap of the nat setup.
Any suggestions would be greatly appreciated!
edit--- the lan interface on pfsense should probably say lan subnet. The interface ip is 10.20.88.105.

Sounds like you don't have any Virtual IPs configured for the "external" addresses of the 1:1 NAT.

Thanks. It ended up being a configuration error. I had a gateway defined on the lan interface. I removed the gateway and added a static route for the lan subnets and everything starting working properly.
