Asus RT-AC68U - UPnP problem - Asuswrt-Merlin firmware

[kemperkipie]

I've got an Asus RT-AC68U in my network. Now is the problem that I've connected it directly to my provider, which basicly works.

Problem is, my provider put me in quarantine-network because I had UPnP enabled.. Now I've disabled it, because I simply don't use it at all. [back at normal network after contact with provider] Only my router doesn't seem to like it. It keeps giving me disconnects and errors.

Here's a piece of the log:

Why this:
Feb 18 21:42:55 rc_service: ip-up 1071:notify_rc start_upnp
Feb 18 21:42:55 rc_service: waitting "stop_upnp" via ip-up ...
I don't want UPnP, and think this is causing the problem!!
I've disabled it in my router, and even black-listed UDP port 1900 from 0.0.0.0 to 0.0.0.0

What else can I do?

Did you post this question over at SmallNetBuilder ? There are lots more Merlin FW users there (and Merlin himself). If you can't get help there I bet you are out of luck.
