Ladies and Gents,
Following upgrading to 7.5xx our customer experienced disruption to traffic flow. See below. This is one of half a dozen streaming audio stream providing a total upload bandwidth of just over a meg.

Anyone any ideas what might have changed in 7.5xx to disrupt traffic flow?
Background
- they are on an IP licence so performance not a suspect as an issue.
- over 365 days, never had any issues on prior versions 7.4xx and back
- you can even see when the audio stream when from 64 to 128k last year
- there is no web or email filtering
- 1 Mbps upload traffic
My suspicions
- something in routing causing packet drop
- something in IDS causing packet drop
Anyone else suffered disruption of traffic and especially if you have found a solution.
I have tried Astaro support, but unfortunately because we have no logs (we had to reinstall 7.4xx to recover a working firewall) they cannot currently help.
Any feedback or suggestions much appreciated.
Best Regards,
