1. It is only possible to see if FIPS mode is enabled on the GW
2. The status of FIPS mode can be seen by:
ckp_regedit -p "software\\checkpoint\\SIC\\FIPS_140"
or
ckp_regedit -p "software\\checkpoint\\SIC” and looking for fips registry

3. Enabling FIPS mode does not change the cryptographic library (there is a single library on the GW) or protocol implementation of SSL VPN (including TLS 1.2) and it should be noted FIPS does not validate protocols, only crypto algorithms (it does validate Key Derivation Functions - KDFs)
5. For configuring cyphers refer to sk126613: Cipher configuration tool for Security Gateways
