If it's not in any attached network it's not "near" either. I'd call this "far" enough. Frankly, I don't want to debate semantics for the configuration you chose to apply. You seem to have your reasons for not having a gateway that is locally reachable so you need to configure it as such.Cheers,Franco
And as I explained in my second message: "We have also been able to create the gateway without using "far", but it requires to Apply configuration first: so my guess is now the check is made on the "current" IP address and not the new one."
