topic since you see authentication in Network Access Control

Remote VPN, successful authentication but no connection

isk-admin — Mon, 11 Mar 2019 04:32:00 GMT

Mobile users (WinXP, WIN7) use VPN-Client (5.0.07.0410 and some earlier for WinXP) to access our headquarter on CISCO ASA5520, V8.2(3). At different internet access points (German DSL like unitymedia) I see a successfully authentication (CISCO ACS 4.2 with Database Group Mappings to our Windows AD) but the connection is not closed. The client don´t get any messages back and no pop-up appear for another authentication. We can repeat this process any time by clicking CONNECT again. On other internet access points (German Telecom or local provider) it works very well. Whats going wrong?

Thanks for any help.

since you see authentication being passed, I guess there is some issue with phase 2.

Can you run "debug crpto ipsec" and try to connect again.

Also provide me the o/p of

show crypto ipsec sa

show crypto isakmp sa

show run group-policy <group-policy-name>

show vpn session-db summary
