I am running AnyConnect to work with one of my customers. Another customer is now asking me to run Cisco VPN Client. When I try to run the VPN client the connection fails with:
15 13:12:28.108 11/04/2010 Sev=Critical/1 CVPND/0x43400012 Unable to bind to IKE port. This could be because there is another VPN client installed or running. Please disable or uninstall all VPN Clients other than the Cisco VPN Client.
AnyConnect is not running and I can find no setting in the AnyConnect client to make it unload whatever is causing this. While I don not need to connect to both clients at the same time, constantly uninstalling and reinstalling is just not an option.
How can I deal with this?
OS is Mac OS/X 10.5.8 - AnyConnect is version 2.5 and Cisco VPN Client is version 4.9
The error means that something is still using the UDP Port 500 that the Cisco VPN Client is using.
Applications that we've run into that use it are "Racoon" and the Mac's built in L2TP over IPSec client.
They have two options:
1) Find the other application, disable it, and reboot.
2) They can try manually adding the following keyword to their profile:
