Hi All
We have a VPN setup using a Checkpoint 4.1 firewall and the Lucent Brick 20 firewall. However, recently over the last couple of weeks, we have been getting key installs happening every few seconds. This is making our connection very unstable. I've looked at the Checkpoint logs and they show phase 1 connections happening and then SA Key delete from the Lucent firewall.
After some time, the re-key will be sucessful and if we're lucky it'll hold up. However, frequently, the VPN will just drop again with both firewalls trying once again to do the key install.
Has anyone seen this sort of thing happen before and if so what do you think it could be? I'm wondering whether it could be to do with one of the routers not allowing a particular type of packet getting across the link, hindering the key install process.
Many thanks
