connection issues and workaround - more notes

In my earlier post, I had mentioned restarting management services on Cyberoam as a workaround for connection issues with BUTT live audio streaming. This is of course a very crude kludge, P tried to make a better solution using Firewall rules a couple of days later, giving the TCP packets to the relevant ports to the relevant ip address a higher priority and guaranteed bandwith.

Unfortunately the problem persisted. A couple of weeks later, I had problems. Got disconnected many times in the evening during live. Reconnected within 10-15 seconds every time. My guess is that other usage was dropping the connection due to congestion - it was getting disconnected when Cyberoam shows the peak usage, upload.

I tried making some more firewall rules, by putting in a Bandwidth policy, Other_Usage, and putting it to the rule number 1 on cyberoam firewall rules, ie Any host to Any host all services accept. This bandwidth policy allows 100 kbps guaranteed, 4 Mbps burstable, but with priority 2. The live streaming rules have priority 0 as P had created.

Even this did not solve the problem, sometimes even now there are connection issues when there is a lot of video streaming (youtube etc) traffic from Studio. Probably using only essential services and not doing bandwidth hungry tasks during the live times would be the solution.
