I am running Ubuntu 12.10 and trying to connect to a fortinet VPN server. I use forticlientsslvpn_linux_4.0.2254.

When I try to connect, error occurs during the PPP negotiation (got message Discarded non-LCP packet when LCP not open and timeout sending Config-Requests).

I believe the problem is not on the network, because I can connect perfectly fine using my Mac machine from the same network.

Below are messages from forticlientsslvpn.log and syslog.

Thanks in advance!

Today I upgraded to 13.04. And fortinet works again :)

I'm not sure what caused the issue on my 12.10 setup. I hope it helps someone.
