Re: Checkpoint FW-1 Rules



If you need a rule that affects traffic to an from a particular interface
you can create an object just with that interface IP but don't check it off
as a firewall, then just use it in a rule.  This work OK for things like
accepting things like routing updates _at the firewall_. It does not work
for objects that are not part of the firewall.  Occasionally this trick
creates problems when applying the policy when the object is created in
objects.C file ahead of the firewall object.  Delete and re-create trying a
different name or just hoping.

Usually you should not have to do something like that unless your network
has loops and other problems.  You should also make the extra effort to have
specific well defined rules.  IMHO, using a generic rule and then trying to
apply it to an interface makes for sloppy configurations. You should also
have anti spoofing turned on.
