Microsoft TMG

jilalf W/ Alumni Posts: 5 Security Scout

for our access to the internet (everything outside our house) we go through Microsoft Threat Management Gateway filters. Thus most PCs have a client installed to make access seamless and without proxy-password. 

Since I upgraded all clients a few days ago to version 10.0 we have everywhere intermittent accessproblems to the internet. We still can access the network in house. So I suspect a problem of the new client s/w with the TMG client. 

On our F-Secure-server I see constantly clients going offline and back online. Switching off Deep Guard and Webscanning does not help. Complete deinstallation does. So the culprit is either TMG or f-secure. F-Secure did change something related to network scanning. TMG did not. So F-Secure is the suspect.

Until F-Secure 9.32 we had no problems. 

Any ideas how to get around this ? (except for replacing it with some other product - which, btw, in a testscenario does help the case)

    Hello jilalf,


    Please, try to turn off the Firewall. If this helps, please, contact support. It is possible, that they already have a fix for your issue. If not, they will explain you how to collect debug logs for further investigation.

    Hello jilalf,

    We also have the same problem. Did you find a solutions? We tried to contact support,collected debug logs for them but they didn't find the solution. We ended in infinity loop with them, they sey try this, try that and no filal solution. At the end we gave up, and stayed with 9.32. But yesterday the same problem started with 9.32. Did you find any solution, and what support told you about problem?


    Best regards

    1. We got a solution. 2. Switching off the firewall component can not help, as in-house machines have switched off the firewall permanently. 3. Another problem was the high amount of false positives - which required me to constantly check files, which were OK. So the solution for us was: dump fsecure in favor of a better product. Sorry to say this, but these are our results.
