Do you mean these options under Interfaces > WAN? I have them disabled after they did show up as a block in the log.

There is an opensense option that blocks rfc1918 traffic on the wan. your wan ip addeess range matches rfc1918. I do not remember where to disable it exactly, but this is the error.

I wrote it in reply to another comment, but the traffic reaches the service on 10.0.0.22:8888. The problem seems to be with the return path, i.e. Hairpin NAT, but I don’t know what it is.
