This is wierd - no access to OWA - 31.Oct.2004 1:00:00 PM

I have a ISA2004 with two NICs (10.0.0.2 on Internet and 10.1.80.1 on LAN) and on the LAN there is an ExhangeServer2003 (SmallBusinnessServer) 10.1.80.2. The official IP is 212.222.222.232. I have a configured DNS-server at my ISP and I am able to ping owa.server.com and resolve it to an IP-address.

I have followed Liran Zamir's article and tried to publish my OWA. The certificates works fine, I have created the owa.server.com = 10.1.80.2 in the hostfile on the ISA, and if I connect to owa.server.com/echange on the ISA it works fine.

But - if I try from another computer from the LAN it can't connect and the browser just showes "The page cannot be displayed".

The log on the ISA looks a bit strange:

31-10-2004 12:43:42 - Dest 10.0.0.2 - Dest Port 1 - Unidentified IP traffic - Denied connection - default rule - Client IP 212.222.222.232 - Source Net External - Dest Net Local Host.

31-10-2004 12:43:48 - Dest 212.222.222.80 (ISPs dns) - Dest Port 53 - Initiated Connection - ISA36-Rule - Client IP 10.1.80.4 - Source Net Internal - Dest Net External.

31-10-2004 12:43:50 - Dest 10.0.0.2 - Dest Port 1 - Unidentified IP traffic - Denied connection - default rule - Client IP 212.222.222.232 - Source Net External - Dest Net Local Host.

31-10-2004 12:43:53 - Dest 10.0.0.2 - Dest Port 1 - Unidentified IP traffic - Denied connection - default rule - Client IP 212.222.222.232 - Source Net External - Dest Net Local Host.

31-10-2004 12:43:59 - Dest 10.0.0.2 - Dest Port 1 - Unidentified IP traffic - Denied connection - default rule - Client IP 212.222.222.232 - Source Net External - Dest Net Local Host.

31-10-2004 12:44:09 - Dest 212.222.222.232 - Dest Port 443 - HTTPS - Failed connection - ISA36-rule - Client IP 10.1.80.4 - Source Net Internet - Dest Net External.

Is there anybody that can tell me what is going on? All other traffic through the ISA is working fine. I can also browse external HTTPS-sites without any problems. But for some strange reason the ISA will not publish the OWA.

Kind regards
