Re: SSL VPN in Concentrator

according to cisco press

if you are using WebVPN for remote access and you want to use HTTPS for management access on the concentrator, you'll need to go into the concentrator's public interface (Configuration > Interfaces > Ethernet2 (Public)) and click the Allow Management HTTPS sessions check box. Also click the Redirect HTTP to HTTPS check box to enhance your security, redirecting any HTTP access to HTTPS. Then, to access the concentrator's public interface for management access, enter either of the following URLs in your web browser's address bar:

https://public_interface_address/admin.html

https://public_interface_address/access.html

good luck

please, if helpful Rate

Re: SSL VPN in Concentrator

for more info

To change or modify these management access applications, go to Configuration > System > Management Protocols. I would recommend that you disable HTTP and Telnet and only use HTTPS or SSH because these encrypt the management traffic from the administrator's desktop to the concentrator. To set this up, click the XML hyperlink on this page. XML allows you to enable management via HTTP or XML via HTTPS. By default, HTTPS and SSH are dropped on the public interface by this interface's filter. You could add these rules to the filter manually, but it's much easier to click the check boxes on this screen and let the concentrator automatically add themif you already have enabled WebVPN, HTTPS will already be enabled and will be grayed out on this screen. From this screen, you can optionally restrict who is allowed to come into the public interface via HTTPS or SSH.

also try to use deffrent PC

check if there is a filter ACL or somthing on the concentrator or any device in the path

good luck

Re: SSL VPN in Concentrator

no luck simply headache. dont know what the hell is wrong. Two concentrators are working fine only third one is giving me problem. tried all the things that u mentioned dont know what is getting wrong. disable and enable http,https, restart and even regenerate the ssl certifcate. but not able to access the concentrator via public interface IP address.

I check the public interface filter setting it is the same as i have on rest of the concentrator. Publich filter is allow http,https traffic.

What else left.
