![]() ![]() ![]() The domain name can contain periods, hyphens, and alphanumeric characters. The domain name must start and end with an alphanumeric character. Local hosts (the Security Gateway and network objects) are optionally appended with the domain name when DNS resolving is performed.ĭNS queries that do not contain a domain name are automatically appended with the domain name. There are two separate uses of the domain name: When selected, the local DNS servers resolves network object names to their IP addresses for internal network clients.Įnter a Domain Name.

Security researcher Dan Kaminsky, who uncovered this vulnerability, runs a blog where he discusses this and other issues, but also offers a way to check your DNS server. This option is global and applies to all internal networks. If Internet Connection High Availability is enabled, the DNS servers switch automatically upon failover.īy default, the Check Point Appliance functions as your DNS proxy and provides DNS resolving services to internal hosts behind it (network objects). The gateway uses the DNS settings of the currently-active Internet connection (in case of static IP – the DNS manually provided under "Internet connection"-> Edit, in case of DHCP / Dialers – the DNS automatically provided by the ISP). The second option allows a more dynamic definition of DNS servers. In this case, all DNS requests from this branch office are directed to these DNS servers. ![]() Use the first option if your DNS servers are located in the headquarters office. If you select Configure DNS servers, make sure that you enter valid IP addresses. Select to define up to three DNS servers which is applied to all Internet connections or use the DNS configuration provided by the active Internet connection (Primary).
