I have a single PIX to ASA (site-to-site) IKE tunnel with 2 IPSec tunnels,
Tunnels come up no problem after sending interesting traffic, but after around 30 minutes of no traffic - the tunnels drop.
Again after interesting traffic is sent they come back up.
Our other PIX to PIX VPN's are fine and seem to stay up for long periods of time, which leads me to believe that the "keep-alive" or similar is not working right.
Anyone have any ideas to fix this?
