I know that 264/tcp is used by securemote to get the site information, and that 500/udp is for IPSec. Does anybody know 
what 18262/tcp and 18264/tcp is used for? It seems questionable...

    Subject: Penetration Testing a CheckPoint NG FW on Nokia
      I was recently performing a penetration test against a
    CheckPoint FW running on Nokia and received the
    following results from a port scan against the host:
    
    Interesting ports on XYZ:
    (The 65531 ports scanned but not shown below are in
    state: filtered)
    PORT      STATE  SERVICE          VERSION
    264/tcp   open   fw1-secureremote Checkpoint Firewall1
    SecureRemote
    500/tcp   closed isakmp
    18262/tcp closed unknown
    18264/tcp open   unknown
    
    When telnetting to TCP 18264 I received:
    
    HTTP/1.0 400 Bad Request
    Date: Wed, 05 Jan 2005 21:57:57 GMT
    Server: Check Point SVN foundation
    Content-Type: text/html
    Connection: close
    Content-Length: 200
    
    Opening a browser to TCP 18264 gave an "Internal
    Server Error".
    
    Are there any tools that allow me to brute-force a
    username and password through the SecuRemote port to
    gain unauthorised access via VPN?
    
    I found this link for bruteforcing usernames on
    CheckPoint -
    http://www.securiteam.com/securitynews/5TP040U8AW.html
    but could not find the supporting tools. Does anyone
    have this set of tools? and other password
    bruteforcing tools?
    
    Are there any security implications of allowing access
    to TCP 18262 and TCP 18264 ports? What will break if
    these ports are closed?
    
    Does anyone have a list of other tests that should be
    performed against a CheckPoint FW?
    
    Cheers,
