"Automatic outbound NAT rule generation" not works when the WAN not public IP

[veptune]

Hello all,

My WAN and LAN interfaces have both private IP (as I my OPNsense is in AWS VPC).

I have use the defaul setting for NAT :

Automatic outbound NAT rule generation
(no manual rules can be used)

But the NAT was not done. I had to select

Hybrid outbound NAT rule generation
(automatically generated rules are applied after manual rules)

is it normal?

Thanks

Not for me but I don't use AWS VPC. It looks like you have no WAN-type interface, only LAN-type interfaces. Set the gateway in the interface config of your WAN (IPv4 gateway rules).
