I am trying to connect via Cisco VPN client. Tech support at the remote computer end has no idea what the problem is, so for now I'm on my own. When I try to log on, I get the error: "Secure VPN Connection terminated by Peer. Reason 427: Unkown Error occurred at Peer." . I've uninstalled and reinstalled the client, I installed it on a second computer, and in all instances I get the same error. I can connect to other companies using the same VPN client install.
The only thing that I can find about potential problems is to switch the transport setting from IPSEC over to IPSec over TCP. But I would need a Port number. What Port number should I use? Or what can I direct tech-support where to look to determin. It has 10000 by default and that didn't work. I also tried unchecking Enable Transparent Tunneling.
Also, for troubleshooting, I enabled logging. However the log does not show any error or information related to this problem.
