NAT Rule

Good Evening.

I hope everyone is well. I got a question about the new NAT rules, something I dont understand, might be my lacking understanding at all in this field. However, could anyone tell me what does this Original source field mean? I thought for an outgoing nat roule, the source is just LAN,WIFI, but I cant choose that, instead it lists up countries??

Thank you for your reply. But I still dont get it. I am sorry.

I understand, but if I want to create an outgoing rule only, I still have to choose any? I cant pick nothing?

So pre nat of outgoing should be LAN?

Hi AussieTom

You can leave Any if firewall rule LAN to WAN has internal network specified under "Source networks and devices" or remove Any and add your internal network as original source.

If you are trying to create decoupled NAT rule for outbound traffic, please select MASQ profile under "Translated source[SNAT]".
