We have a IPSEC tunnel set up between our ASA and a Barracuda NG on the other side. The tunnel is functional, except it seems to have a very short idle time-out (couple of seconds) and it can only be raised from the Barracuda side.
I feel reasonably confident that ASA side is properly configured (but am open to ideas, in case I'm wrong) but I have no idea about Barracuda. If anyone knows that device - What are we missing? Where does the keep-alive get set? And, why can the tunnel only be opened from their side?
Any help is much appreciated.
