I am having some problem with my vpn client. My cisco vpn automatically disconnects. I don't know why. It is saying Connection VPN connection terminated locally by the client. Reason 422.Lost contact with the security gateway. Check your network connection.

A VPN can disconnect for a number of reasons:

  • when the VPN disconnects, do you still have internet connection?
  • can you still ping the endpoint (the remote gateway) on both DNS name and IP?
  • is the VPN idle? Some VPN connections tend to disconnect when being idle and rebuild when there is activity again on the VPN connection.
  • Is there an idle time-out of some sort configured?

These are just suggestions since the information that is given is not much.

Check that the remote system and local host system are not using the same IP subnet. I have seen this cause the client to drop
