Hi All

Have an interesting issue with TMG (SP1 RU1). The configuration was imported from ISA 2006 which included a working VPN. Now if the VPN is enabled and not used there is no issue but as soon as it is connected to then browse performance for internal users is affected. Disable the VPN and restart the firewall service and the performance issue is resolved.

What happens: Internal user, IE8 is opened and any externally hosted webpage is opened. Under normal circumstances this page will load in a matter of seconds and can be repeated time after time with multiple users. Then a VPN connection is made. This cnnection works as expected and again is repeatable. However now internal users access an external website and the page will take upto 90+ seconds to load (regardless of VPN connections). Once the page is loaded browsing within that site appears OK but access a new site an the issue is present. Add to that, open a new tab in IE and select something from favorites it will will never load. Type a URL in and it will.

Of course nothing in the event logs to give me a clue so can anyone suggest things to try.

Thanks
Bruce

Hi Bruce,
