RE: [Users] x509 and checkpoint fw-1

In the first place it is strange that you cannot configure
fw-1 to send you a DN or a FQDN ID. But if you are really
stuck with an IPV4_ADDR then the only thing you can do is
to extract the public key from the fw-1 certificate using

  fswcert -c --left fw-1.pem

and paste it into ipsec.conf:

  left=138.189.119.132
  leftrsasigkey=0x.......

Unfortunately for you Pluto will not accept

  left=138.189.119.132
  leftcert=fw-1.pem

since there is no subjectAltName for the IP address
contained in the certificate.

Regards

Andreas
