The problem is simple: I cannot log into the AP from another network on the opposite side of the firewall. It sounds like an access issue but it is not, as I have done any/any on both ends and every communication works except the AP105 web interface. I can ping it, but when I try to web access it gives a very fast error: access denied. I've tried two browsers with the same result. When I do https, I get the cert error, which is normal. But then progresing through that I get the access denied error again. I can access this just fine on the local wifi network.
I can't get myself to blame the firewall because everything else works, and I can't blame the routing because it's a one-hop and again, everything else works.
Is there a security setting I may be missing here?
