DPD and Keepalive

[Zsolt Balog]

Hello!

I'am using Ubuntu 13.04, Network Manager with openconnect. I can
connect, but after 2 or 3 seconds (no traffic), my connection dead,
and after 10 seconds the server disconnect with 'Idle Timeout'.
When VPN get connected, in the syslog:
 openconnect[12146]: CSTP connected. DPD 0, Keepalive 0

Can I set the DPD and Keepalive value for the connection?

Thanks!
