VPN gateway not responding (waiting for Msg 2)

Does anyone know what this error means from a Cisco VPN client when trying to connect to a ASA 5510?

VPN Error

VPN gateway not responding (waiting for Msg 2)

Thanks for any help!

Hi,

It means the VPN Client has sent message 1 to the VPN device but it hasnt received the reply (message 2) from the VPN device.

So either

• Message 1 doesnt reach VPN device
• VPN device doesnt have a route back to VPN Client to send Message 2
• Something on the way is blocking the messages in either direction
• Something wrong with the VPN configurations on the VPN device
• etc

Could the windows firewall be causing this? I usually assume it will not block anything outbound.

Thanks for the response!

Hi,

To be honest everytime I have run into problems with the old VPN Client software it has either been some simple local network problems or problem with the actual host PC. Its been very rarely that I have had a VPN device cause the problems with the connectivity. Its very rarely been problem with the routing in the public network either.

Have you been able to monitor the ASA while trying to connect with the VPN Client.
