IPSec tunnel instability

I am running 2.0 RC3 (hope to upgrade soon), and I am finding that my IPSec tunnels to various devices (Linksys RV042, Cisco PIX, Watchguard Firebox, etc.) will tend to go down on their own unless I am sending traffic constantly through the tunnel with OpenNMS.
I recently made a change to allow UDP 4500 on the firewall as well as UDP 500. Will this help my stability problems or do I need to make some other change? I do configure the Phase 2 monitoring IP address, but this does not seem to keep the tunnel stable without traffic going through it originating from my end.

IPsec connections don't stay up unless you're sending traffic across them. Though that generally doesn't matter, as soon as something tries to send something across they'll come up within 1-2 seconds. As long as the local subnet includes one of the IPs assigned to the firewall, the ping host will keep it up.
