Dear All,
This is regards to Anyconnect SSL VPN.
One of my customer is using the below scenario. He is trying to connect to 2 gateway for vpn access. Gateway 1 (Router) is using anyconnect 3.0 version and Gateway 2 (ASA) is using anyconnect 3.1 version and windows anyconnect client is of version 3.0.
When he is trying to connect to Gateway 1 he is not facing any issues but when he is trying to connect to Gateway 2, his windows anyconnect client automatically upgrades to 3.1 and prompts with "Untrusted VPN server certificate error" and now again when he tries to connect the same to Gateway 1 he is facing the same "untrusted server issue". We tried downgrading the "anyconnect client" to 3.0 version on the windows machine and he is able to connect back to Gateway 1, but the issue is when he try connecting back to Gateway 2, the client upgrades again and unable to connect it.
1) Can we stop anyconnect client on the windows machine to stop auto upgrade ?
2) How to sort out this "certificate error"
Awaiting experts to provide me the solution.
Best Regards.
VR.

Hi Pankaj,
The issue is even if we downgrade to any mentioned version, when tried to contact to gateway2 which has anyconnect 3.1 version (where the gateway is not managed by us), the client automatically upgrades to 3.1 and causes "vpn server certificate error".

In that case upgrade anyconnect pakcage at gatway1.
(router). you can do it ,you just need to Download it from Cisco website.
You can't stop anyconnect to be auto upgrade. If it won't upgrade it won't connect.
