Just stumbled over a problem, where I can't figure out whats going wrong. So im looking for some suggestions and where is a better place to ask than on this forum
I have an ISA 2004 server configured for VPN. It all works, people can log on and can reach the servers inside and the surf the Internet. The only thing there aint working, is when people try to reach a HTTPS site through VPN.
The rule I have setup to allow HTTP and HTTPS from VPN Clients to External is:
Name Action Protocol From/Listener To Condition VPN Client to Internet Allow HTTP, HTTPS VPN Clients External All Users
I have no changed any thing on the two protocols HTTP and HTTPS, they are just added with the default settings.
From a VPN Client it receive a "The page cannot be displayed" when I try to open a HTTPS site, normal HTTP works fine.
When I look in the monitoring on the ISA server I see the following:
Destination Protocol Action Rule Source Network Destination Error Information Result Code 443 HTTPS "Initiated Connection" "VPN Client to Internet" "VPN Clients" "External" 0x0 0x0 443 HTTPS "Closed Connection" "VPN Client to Internet" "VPN Clients" "External" 0x0 0x80074e21
It seems that https port is not getting through the VPN. For a test purpose, edit your rule" VPN Client to Internet" and allow all protocols and see whether the client can access the https sites. Post the result.
