Hello,
we changed our main-firewall from ASG220/V8.x to ASG320/V9.109-1 and disabled Spotify-traffic via the flow monitor - 10 minutes later we got the message from our supporters, that PPTP connections to our customers are not possible any more.
Looking in the packetfilter log we found that the traffic on port 1723 from the remote peer to the WAN-interface will be blocked by rule 60001 .. by searching the Bulletin board we found an identical thread in UTM Beta 9.2 section.
So we disabled the Spotify-rule in Application control rules and - violà - PPTP through the Sophos was working again.
.. no further comments ..
Christian
