Stlpaul, can you please elaborate on the actual command line you add "--dpd-idle=0" to in order to keep from being disconnected?

Essentially I am looking for the complete command since I cannot seem to get it running without it disconnecting after a while.

On the Vpnc web site I found the following two notes:

# disconnecting does not work reliable with all supported targets (a work-around is to connect with incorrect password, and then again with correct password)

# vpnc looses connection with some targets, even before the rekey-timer expires most probably due bugs with keepalive, dead-peer-detection or something else...
