Name Service Providers

Note

IP pooling is configured per groups, as described in “Enabling IP Pooling” on page 94.

Name resolution is configured on the Name Service Providers tab. You can specify the following:

DNS Server 1, DNS Server 2, DNS Server 3

These are the IP address of the first, second, and third DNS servers.

DNS suffixes

These are the DNS suffixes of the servers. Each entry in the list is separated by a space. Each entry should follow the format of site.com. Do not precede a suffix with a dot (“.”), such as

.site.com.

By default, the Firebox SSL VPN Gateway checks a user’s remote DNS only. If you want to allow failover to a user’s local DNS, you need to enable split DNS.

WINS Server

This is the IP address of the WINS server.

To have client connections communicate with the WINS Server, the IP address must be manually added to the Accessible Networks list on the Global Cluster Policies tab. For more information, see “Controlling Network Access” on page 56. The IP address must also be added as a network resource on the Access Policy Manager tab and added to the user group(s). For more information, see “Defining network resources” on page 99.

To enable split DNS

1On the Access Policy Manager tab, in the left pane, right-click a group and click Properties.

2On the Networking tab, select Enable split-DNS.

The Firebox SSL VPN Gateway fails over to the local DNS only if the specified DNS servers cannot be contacted, but not if there is a negative response.

To edit the HOSTS file

You can add entries to the Firebox SSL VPN Gateway HOSTS file from the Name Service Providers tab. The Firebox SSL VPN Gateway uses the entries in the HOSTS file to resolve FQDNs to IP addresses. When the Firebox SSL VPN Gateway attempts to translate an FQDN to an IP address, the Firebox SSL VPN Gateway checks its HOSTS file before connecting to DNS to perform the address translation. If the Fire- box SSL VPN Gateway can translate the FQDN to an IP address using the information in the HOSTS file, it does not use DNS to perform the address translation.

You might want to add entries to the HOSTS file in an Firebox SSL VPN Gateway deployment where the network configuration prevents the Firebox SSL VPN Gateway from connecting to DNS to perform address translations. Also, adding entries to the HOSTS file can optimize performance because the Fire- box SSL VPN Gateway does not have to connect to a different server to perform the address translations.

To add an entry to the HOSTS file

1On the Firebox SSL VPN Gateway Cluster tab, open the window for an appliance.

2 Click the Name Service Providers tab.

This could involve mobile device verification or biometric authentication, significantly reducing the risk of unauthorized access.

Another key characteristic of WatchGuard’s SSL VPN is its integration with other WatchGuard security solutions. Businesses can benefit from a comprehensive security posture by leveraging firewalls and intrusion prevention systems along with the SSL VPN. This holistic approach ensures that remote connections are continually monitored and secured against evolving cyber threats.

Scalability is also a crucial aspect of WatchGuard's SSL VPN, accommodating growing organizations with changing needs. The solution can easily scale to support an increasing number of remote users without compromising performance.
