This section addresses some questions that are frequently asked about VPNs in FireWall-1.
Generally, yes. It is usually a matter of making sure the settings match on both ends of the VPN. This is made somewhat difficult because each vendor refers to a particular setting with a slightly different name. For known interoperability issues with some third-party VPN products, see FAQ 11.17.
In NG FP2 and FP3, there is an issue that requires a hotfix for interoperating with a Cisco PIX. For FP3, request hotfix SHF_FW1_FP3_0006 from Check Point Support. For FP2, request hotfix SHF_FW1_FP2_0248.
