FireWall-1 FAQ: Secure Client and Compatible FireWall-1 Versions/Features

Please note: This content was from when I was operating my FireWall-1 FAQ site, which I stopped operating in August 2005. For some reason people still have links to this stuff on the Internet that people are still clicking on.

I am making this information available again AS IS. Given how old this information is, it is likely wildly inaccurate. I have no plans to update this information.

If you're still running versions of Check Point VPN-1/FireWall-1 where this information is still relevant to you, do yourself a favor and upgrade to a more recent release. If you happen to be running a current release and the information is useful, it's by happenstance :)

Any version of FireWall-1 2.1c or later is compatible with any version of the SecuRemote Client. Older versions of FireWall-1 tend to work with newer versions of SecuRemote, but newer versions of FireWall-1 do not always support older versions of SecuRemote. NG requires you to use the NG version of SecuRemote. I’ve also heard reports that 4.1 versions of FireWall-1 do allow 4.0 or earlier versions of SecuRemote to connect. One should always be running the most current version of SecuRemote, especially since you can download it from Check Point’s Download Page without a password.

Certain functionality requires certain versions of FireWall-1 and/or SecuRemote. See the table below for specific functionality:

If using the Policy Server component, your client must be the same major version as your firewall (e.g. a 4.1 client cannot use an NG Policy Server).

Note that if you wish for FireWall-1 4.0 or later to support 3.x SecuRemote clients, you will need to make sure the “Respond to unauthenticated cleartext topology requests” option is checked in Rulebase Properties under the Encryption tab.
