Hello All.

I have a interesting probem. We have a client trying to access another client's ASA 5510 using Cisco VPN client. The client terminates with Reason 433. This has been going on with the client in question for a couple days now. I'm just wonder what the reasons could be that would cause this and what we can do about this. Could the VPN connection be terminating do to high bandwidth usage on the other end. I installed the newest version of VPN which is 5.0.02.0090. I am including the Cisco ASA on the receiving end of the VPN connection. Any suggestions? Thank you.

There is a VPN idle timeout specified for one thing.
" vpn-idle-timeout 30"
Try removing that. You will likely need to do it from the command line as ASDM is a bitch about removing things like that sometimes.
telnet in and go to enable, then conf t
group-policy ACACIA attributes
vpn-idle-timeout none
end
write

test!

Thank you. I've seen that I I removed it. I was at the clients location today and connected to the other network with her machine and my laptop for 30-40 mins through VPN. The connection was stable. We have nagios running with Bandwidth monitoring and I checked that. The line did not appear saturated at any time when the connection dropped. We never had an issue before a couple days ago. It could be the ISP. Sprint that provides the private line reports no issues with the line.

In that case I would suggest it might be ISP related. You could try reducing your MTU a bit - there should be a tool for this installed with the EasyVPN client.

Im have the same problem until I reload the ASA and it turns out that there is a memory leak in my version 8.03(6) and was suggested by Cisco to upgrade or downgrade. You may have the same problem. Reboot the ASA and try to VPN in.
