Our ASA was working perfectly fine for remote VPN and SSL VPN but Not sure what happened it stop establishing remote VPN and SSL VPN sessions, we're working on ASA but now remote VPN, SSL VPN users can NOT logged in to the corporate network. I've checked every thing but I don't know what's missing. When I run show crypto isa sa command I get message no crypto isa, but when I compare the configs crypto is there. I've rebooted the ASA but no luck. User are able to logged in via secondary ASA.
1. Remote vpn try to initiate connection to c2.twu.com
2. gateway ask for user name / password
3. after password no response and message shows on vpn client status bar establishing session ......................
4. show crypto doesn't shows any active/inactive session info
similar things are happening when I try to initiate a session via SSL VPN, it comes to authentication page, once I enter the login credential but does nothing.
ASA Ver 8.0.3
