Hi guys,

we are working with our SIP providers to set up VOIP through the TMG server. The requirements are to allow UDP ports 10k-60k from the SIP IP address to our internal VOIP server (trixbox). 

intially they had asked not to Limit 10k-60k instead allow all UDP ports be forwarded to the internal VOIP server. so i created the rule and put in the UDP port range of 0-65535, send receive.

Enabled the Rule, and as soon as the tmg server updated the configs, wspsrv.exe started consuming all memory.

Internet access died and had to reboot the server manually so that i could disable the Rule.

Next the SIP provider asked us to enable 10k-60k and not maximum UDP range. which i did, also provided 24GB memory to the server and see what happens. memory consumption increased from 15% to 22% and stopped there. Server seemed to be stable, but again internet access started to fail for users. Issues came up such as DNS error, connections randomly dropped.

we have again disabled the rule, and now building another machine so that i can test the same configs on another server and not affect production server.

any one has similar issues? any suggestions/solutions?

I see the issue 1 above where opening all UDP ports has been highlighted here.

Hi,

Can you find any error information or prompt on TMG?

Best Regards

Didnt have to look for any errors, actually, i dont think i would have found any.

Before getting into that, i found a solution (work around) posted here....
