And here is the current NAT file...

nat {

I'm working from the examples here...

just comparing my Nginx rules to yours, it all looks laid out right.

JaredBusch

Did you apply the firewall rule to the interface?

I've even rebooted!

JaredBusch

Do you have a source rule to match this? or does the source rule work on the default masquerade? i.e. you only have a single static IP involved here.

JaredBusch

You can see in my RDP rules that I have a source rule setup because it is a different IP than the default IP of the router.

I just removed the source rule to test. There is only one static IP at the moment.

Got it working. The firewall rule was in the wrong section of the firewall.

You had it on eth0 local instead of eth0 in?
