V7.052: Connection to Exchange 2007 via SSL takes up to 20 minutes

Hi there,
I just searched for a thread like this, but didn't found.
We use a ASG7.502 and have the problem that the connection of Outlook 2007 trough the ssl-vpn to Exchange 2007 takes about 15 minutes. Anything else is working fine.[:(]
I don't think that this occurs of a wrong rule, 'cause after the approx. 15 minutes everything is fine. The IPS is disabled.
Did anyone have an idea?

thx Noisy

Do you have ports limited through the VPN?
If you don't RPC over HTTP proxy (Outlook Anywhere), all ports above 1024 have to be open.

I tried to use the rule SSL-Usergroup ANY ALLOWED to Internal Network. So I don't use any port limitation through VPN, right?! Unfortunatelly it doesn't run better...
RPC over HTTPS isn't active. So the communication to the Exchange is only allowed trough VPN.

Hmmm, that should work.
Have looked into the package filter live log while trying to connect if there are any denied packages?

are you using a static IP for your Exchange server with any DNAT rules?
