XBMC & upnp not working with firewall

Hi all,

I'm having a weird issue with XMBC and its upnp functionality. After scouring the net and the awesome wiki, I opened ports 1900/udp & 2869/tcp in ufw:

[root@bolvar ufw]# ufw status
Status: active
[root@bolvar ufw]# ufw allow 1900/udp
Rule added
Rule added (v6)
[root@bolvar ufw]# ufw allow 2869/tcp
Rule added
Rule added (v6)
[root@bolvar ufw]# ufw status
Status: active

To                         Action      From
--                         ------      ----
1900/udp                   ALLOW       Anywhere
2869/tcp                   ALLOW       Anywhere
1900/udp                   ALLOW       Anywhere (v6)
2869/tcp                   ALLOW       Anywhere (v6)

But XBMC will not find my upnp server (A Synology DS411slim); when I disable the firewall fully, it works...

The biggest difference I can think of since it last worked was installing sytemd. Has systemd changed something that I'm missing? I want to debug this myself, but I'm confused as what to do next.

Below is a snippet of my dmesg output if this helps:

Interesting... after trying literally for minutes to connect, XBMC suddenly found the server. Very inconsistent and with no changes.

After a reboot this is still not working. Any ideas on what to check/fix?

Thanks.
