I enabled UPNP based on this guide:
http://wiki.mikrotik.com/wiki/Manual:IP/UPnP
Seemed simple. Enable it, set pppoe-out1 as external interface and bridge1 as internal. DHCP server and internal IP pool etc are all on bridge1.
The test utility here claims it is not working.

Anyone have uPNP working on Mikrotik? Perhaps test utility is wrong. But I have another program claiming uPNP test has failed.
