cp2fwbuilder, or Checkpoint Firewall 1 to FwBuilder. This tools help you to migrate an existing Checkpoint Firewall 1 Installation and its Rulesets to Linux with iptables or *BSD based Firewall. This is done by converting the Rulebase- and the Objects- Database from Checkpoint to the FirewallBuilder XML Format.
Remember though, that this program is under development and could eventually do nasty things when doing the translation. especially with things like Userauthentication or Clientauthentication which are not supported under fwbuilder. Usage:
cp2fwbuilder
[--objects=]
[--rules=]
[--all_objs] [--all_services]
[--with_implicit_rules]
[--sort_by_type]
[--verbose] [--version] [--comments]
[--output_xml=]
cp2fwbuilder --objects=objects.C --rules=rulebase.W --output_xml=rulebase.xml
fwbuilder -f rulebase.xml
