Description (partial)


- host block is placed
- communications between IPS and firewall device are temporarily disrupted
- host block is removed (or expires)
- communications recover

In such a case IPS thinks that the block no longer exists, but the block is still in place on the managed device. The IPS doesn't send "no block" command to the managed device when communications are restored.

All IPS versions.
