OpenVPN Logs "IP Packet with unknown IP version=15"
On my OpenVPN server, I’m getting messages from OpenVPN like:
ovpn-server: host/192.168.129.155:33454 IP packet with unknown IP version=15 seen
I have three OpenVPN clients and each of them give this error every minute.
A quick Google search makes it sound like this issue happens when one side is not using compression. But, in my setup, both the clients and the server have compression on.
Some of the clients are 12.04 and some are 12.10. The server is running 12.10, but all of the clients give the error.
Any thoughts on this?
