2.5 Configuring DNS Servers

The DNS servers configured in the SSL VPN server are pushed to the client during the connection. When a Linux or Windows client connects to the SSL VPN server, the existing DNS entry on the client is pushed as the secondary entry and the DNS entry configured on the SSL VPN server is pushed as the primary DNS entry.

However, on a Mac client, the DNS entry configured on the SSL VPN server acts as the secondary DNS. After the SSL VPN connection, name resolution is done through the DNS entry configured before the SSL VPN connection. However, when the primary DNS server is not available, the DNS entry configured by the SSL VPN server takes care of DNS resolution for the client.

You can configure DNS servers for Enterprise mode through the Administration Console. The DNS servers can be configured for Kiosk mode either during the installation if you are installing Linux Access Gateway and SSL VPN on the same machine, or by using YaST® after the installation.

2.5.1 Configuring DNS Servers for Enterprise Mode

  1. In the Administration Console, click Devices > SSL VPNs > Edit.

    The Server configuration page is displayed.

  2. Select DNS Server List from the Basic Gateway Configuration section.

  3. To configure a DNS server, click New in the DNS Servers section, specify the IP address of the server, then click OK.

  4. To configure a domain, click New in the Domains section, specify the domain name, then click OK.

  5. To delete a DNS server or a domain, select the check box next to the field and click Delete in the section.

  6. To save your modifications, click OK, then click Update on the Configuration page.

2.5.2 Configuring DNS Servers for Kiosk Mode

The DNS servers can be configured for Kiosk mode during installation or by using YaST after the installation. The configuration procedure depends on whether you have installed SSL VPN and the Linux Access Gateway on the same machine or on separate machines.

NOTE:You must configure the DNS server for both Kiosk mode and Enterprise mode. For information on configuring DNS servers for Enterprise mode, see Configuring DNS Servers for Enterprise Mode.

Configuring DNS Servers during Installation

If you are installing SSL VPN and the Linux Access Gateway on the same machine, you can configure DNS servers during the Linux Access Gateway installation. For more information, see Installing the Linux Access Gateway Appliance in the Novell Access Manager 3.1 SP2 Installation Guide.

Configuring DNS Servers after the Installation

If you are installing SSL VPN and the Linux Access Gateway on separate machines, you can configure DNS servers in the /etc/resolv.conf file by using YaST as follows:

  1. In YaST, select Network Devices > Network Cards, then press Enter.

  2. Select Change, then press Enter.

  3. Select Edit, then press Enter.

  4. Select Hostname and Name Servers, then press Enter.

  5. Specify the IP addresses of the DNS servers that you want to add.

  6. Specify the domain names.

  7. Click OK.

Verify that the DNS servers and domain names are added to the /etc/resolv.conf file.
