I tried several methods (SDM, CCP, CLI) to configure an SSL VPN on a Cisco 871 router for a small office to use the full tunnel client. The office has static IP on AT&T DSL. Currently, after some cert errors, the client finally seems to install but when trying to establish the tunnel an error msg is displayed "The SSL VPN HTTP response code received from the gateway indicates an error." and the connection is ended. Please help! Config attached.
