Firewall/NAT

Hello,
I'm trying to do a route between 2 privates subnets.
I opened the firewall (*, *, *, *,*) from WAN and from LAN.

From the LAN to the WAN, all works properly. I can reach all the addresses on the WAN subnet.

From the WAN to the LAN, It doesn't works... With the log, I can see that the Firewall pass (green arrow), but I can't reach the LAN addresses from the WAN...

Then I've change WAN interface for the OPT1 interface, with exactly the same settings, and it works!!

What's the difference between LAN/OPT1 and WAN interface? With the same settings it works not on the same way...

Thanks!!

The WAN interface is also doing NAT.  If you want it for pure routing you have to turn off NAT.

How do you turn off NAT?
