Hi all,

I have configured remote access VPN with radius authentication in my firewall ( ASA 5510). When tried to connect the VPN with cisco vpn client, the following error is showing,

"Error: Secure VPN connection terminated by Peer. Reason 433 (Reason not specified by peer)"

Kindly help me to fix this issue.

Regards,

Ejaz

I had the exact same issue. It turned out to be the AAA authentication server settings on the firewall. I was authenticating against a Microsoft LDAP server. I think the Logon DN path had some characters Cisco couldn't comprehend. Here is how I fixed it.
