FW: Stale IKE SA on FW-1Chris,
Have you tried to run vpn command after halting one of the cluster members?
They are syncronizing every time you delete that SA.
Maybe, this is a syncronization bug.
good luck.

Dear Chris,
Please Try this:
1. Remove the: "Keep Ike SA's" smartDashBoarda Policy a Global Properties a
SmartDashboard Customization a Configure a VPN / IKE Properties a uncheck
"Keep Ike SA's" (make sure that the externally managed GW guy's do that too)
2. In the cluster object itself: a advanced a connection persistency a select:
rematch all connections.
3. In the cluster object itself: a VPN a advanced a check: perform organized
shutdown (make sure that the externally managed GW guy's do that too)
4. Install the policy to the cluster.
5. Optionally: [Install R61 Latest HFA (if available) to management server
and cluster.]
If the externally managed gw support's the "send initial contact" then
Under: smart Dashboarda Policy a Global Properties a Smart Dashboard
Customization a Configure a VPN / IKE Properties a
Make sure that the settings in the cluster and the settings in the remote
GW are identical (both should send each other)
This should bring order to chaos in the SA's

Hi List,
has anyone ever had an IKE SA that just wouldn't die on a Checkpoint?
The Firewall in question is a (fairly new) R61 clustered on Nokia hardware.
Normally the #vpn tu command should allow SA's to be deleted either singly or
collectively.
I have a stale IKE SA between this gateway and another (externally managed)
gateway that refuses to die. The SA is more than twice as old as the reneg
time, and is just sitting there blocking negotiation of a new one. If I delete
it with #vpn tu absolutely nothing changes and the SA is still showing in the
list.
Have any of you ever seen this before? Does anyone have an idea what I can do?
I have already tried:
- making changes in encryption in the community settings and publishing the
policy
- deleting the object for the remote gateway and the related rules, publishing
and then recreating them
- every possible #vpn tu command, including deleting ALL IKE+IPSec SA's
- banging my head on the wall
I was even considering booting the firewall, but the SA should be synched on
both so I assume that will be pretty useless as the other node will have the SA
as well.
Thanks in advance for any suggestions, I wasn't able to find *anything* on
google about this type of problem.
