The next subsection explains how to configure the VPN in Traditional mode the subsection after that covers Simplified mode configuration. I show how to set up the VPN using both Traditional and Simplified rules in this chapter. If you decide to convert back to encryption rules, you will need to remove all of your gateways from all VPN communities or your VPN will not function correctly. However, you cannot convert from a Simplified configuration to a Traditional one. It is possible to convert an existing Traditional mode rulebase into a Simplified mode policy using the conversion tool present in FireWall-1 NG FP3 and later within SmartDashboard/Policy Editor.

Old security policies maintain their existing Simplified or Traditional states when you change this setting in the VPN-1 Pro frame. This setting determines the mode only for newly created security policies. Once you have decided to go one way or the other, set the appropriate option. Until you have decided which method of creating a VPN is right for you, it is advisable to select the third option listed, Traditional or Simplified mode per new Security Policy. You can determine whether new rulebases are created to use Simplified or Traditional mode by going into the Global Properties section, VPN-1 Pro frame, in SmartDashboard/Policy Editor, as shown in Figure 11.2. If you are using NG FP2 and are setting up VPNs with non?Check Point endpoints (i.e., those endpoints represented as interoperable devices), you will need to use encryption rules. Simplified mode has an important limitation in FireWall-1 NG FP2 and before: You cannot set a pre-shared secret for IKE. This also makes for a far simpler rulebase, particularly when you get into a several-site VPN. A Simplified mode rulebase has a new column, If Via, which allows you to restrict certain types of traffic to be within the context of a VPN (e.g., site-a can talk to site-b only in an encrypted manner). The community also defines which encryption methods will be used between the gateways, which simplifies configuration dramatically. It contains all the firewalls and encryption domains that will participate in a VPN. Traditional mode means defining VPNs the way it was always done in FireWall-1 4.1 and earlier versions, namely, with rules that use the action 'encrypt.' Simplified mode uses a VPN Community, which is similar to a group. Now that you know the necessary information about the different sides of the VPN, let's talk about how to set this up?in Traditional mode or Simplified mode. If a different management station manages one or more of the gateways, you will have to exchange CA keys so that your certificates can be validated. See the next subsection for details.ДЇor certificates, the decision is very easy if the same management station manages all gateways in the VPN and they all run NG: Use certificates, which will be basically automatic. The version of FireWall-1 and how you define the VPN will determine which method(s) you can use. Should you use certificates or pre-shared secrets? The only time to consider using a pre-shared secret is when you are interoperating with either a pre-NG version of FireWall-1 or a third-party VPN. The security policy determines which hosts can actually be accessed. The encryption domain simply contains every network and host that could potentially be accessed through the VPN. It is possible to restrict which hosts are accessible via the security policy. Note that it may not be desirable for every host within the various networks to be accessible. The encryption domain for Site B should include these networks along with any translated IP addresses for hosts on this network. Likewise, Site B has the network 172.17.0.0/16 behind its gateway. The encryption domain for Site A should include these networks along with any translated IP addresses for hosts on these networks. Whether certificates or pre-shared secrets will be used Which hosts and/or networks will be accessible at the remote site (the partner's encryption domain) Which hosts and/or networks the remote site will be able to access through the VPN (your encryption domain) You need the following information when planning a VPN based in FireWall-1: As noted previously in the book, I treat .x as routable address space even though it is generally not considered routable per RFC1918.
