[vpn-help] Connection dropping with Ubuntu 14.04

I have been having the exact same problem and no one has helped me yet! 

I have also tried the following

.         I installed Shrewsoft on Windows XP, Vista and window 7 (both 32
and 64 bit editions).

.         I have re-installed Shrewsoft more time than I can count

.         I have stopped and restarted the Shrewsoft and ISPec services.

.         Tried it when no one else was on the remote or local networks
(2:00 AM)

.         Connected the computer directly into the remote router (no switch
or hub in between)

None of this helps

 

The only thing I have noticed is that the VPN router does not show the user
logged in anymore which explains why all functionality disappears.

 

I am using a Cisco SA540 router. What are you using? 

 

I assume the problem has something to do with Dead Peer detection or Keep
Alive but I have no idea how to set this properly on either the router or in
Shrewsoft. I have just kept the default settings.

 

I would love to keep Shrewsoft since it is much easier and faster to connect
than what Cisco provides. 

But my users (and me) are complaining bitterly and if I can't get this
resolved soon I will have to give up on Shrewsoft.

All,

 

I recently compiled and installed Shrewsoft 2.2.1 on Ubuntu 14.04. It worked
great at first, but recently I've had a problem where the connection will be
made, then drop about 30 or so seconds later. I see these messages in
iked.log after the drop:

 

14/07/31 17:10:33 K! : unhandled pfkey message type EXPIRE ( 8 )
14/07/31 17:10:33 K! : recv UPDATE message failure ( errno = 3 )
14/07/31 17:11:01 K! : recv DELETE message failure ( errno = 3 )

 

The VPN software stays connected, but the connection no longer works. Also,
the first line is the error message I get when the connection quits working.
The other two show up after I drop the connection

 

Does anyone know what causes thankis and what can be done about it?

 

Thank you.
