**********************************************

We are establishing a connection with Cisco VPN Client ver. 5.0.07.0290 to the external VPN Host 95.86.133.30. Connection is established successfully, then we try to open link https://x.x.x.x:7777/accr. This is the link to the system where you are authenticated with a certificate already installed i personal certificate store. Certificate is valid.

Thing is, that if we are trying to do this while behind the ASA - internet explorer displays his favourite "Internet Explorer cannot display the webpage".

If we connect the laptop directly to the internet with public ip address - everything works fine. As I undesrtand the problem is localized - something is missing from ASA configuration. The question is - what?

Will appreciate any help.

Thanks a lot in advance.

Hey,

Glad to know that. I am not sure it's a great idea to have NAT-T disabled though unless there is a specific reason to have that.

Cheers,
