[solved] How to disable nat from lan to wan

[xhark]

Hi,

I'm using pfSense to route between two networks, it works good.

But, I want to disable the output NAT. For exemple, when a PC located on LAN talk with a machine on the WAN pfSense replace the IP address of the PC with the pfSense WAN IP. So, is it possible to keep the original IP address of the PC ?

Thank you for your help.

Firewall –> NAT --> outbound
enable manual rule generation.
Then delete all auto-added rules.

Is it possible to keep input NAT (firewall –> NAT --> Port forward) and disable output NAT ?

Yes this should work.

Thank you, it works.

Operations :
Go to Firewall –> NAT --> Outbound

Check Manual Outbound NAT rule generation (Advanced Outbound NAT (AON)) and Save

A new line appears with LAN Subnet, click on the edit button and Check the first box to disable NAT :

Enabling this option will disable NATing for the item and stop processing outgoing NAT rules.

Click on Save and Apply Changes.
