The one command to clear ALL the connections on a Checkpoint firewall - use with care
Checkpoint firewalls are pretty dynamic and interactive to our changes, for the most of the changes done by administrator it is enough to install the policy for the changes to take immediate effect. In the rare cases when changes (seemingly) do not take effect, it is probably because the particular connection got stuck in the connection table of the firewall. There are 2 ways to fix it: the elegant and the axe way. I will post the elegant way some other day, which includes deleting only the specific stuck connection entry from the connections table, but this post is about the axe way – clearing ALL connection entries from the table in one go. This means, of course, temporary disconnection for all traffic passing the firewall, therefore use it with caution. Here it is:
fw tab –t connections –x
