SSL Mode With Watson versions that support Secure Socket Layer (SSL), se-

cured DDNS services are accessed using HTTPS. Upon connection, Watson vali-

dates the DDNS server's certificate. Use this entry to choose the certificate's valida-

tion method.

None Do not validate the server's certificate.

Chain Validate the entire certificate chain. When selecting this option, the

screen will refresh, displaying an additional combo box for selecting whether to val-

idate the certificate's expiration time. Choose 'Ignore' or 'Check' respectively. If the

certificate has expired, the connection will terminate immediately.

Figure 8-117: SSL Mode

Direct Insure that the server's certificate is directly signed by the root certifi-

cate. This option also provides the 'Validate Time' combo box for validation of the

certificate's expiration time, as described above.

8.6.1 DNS Server

Domain Name System (DNS) provides a service that translates domain names into

IP addresses and vice versa. The gateway's DNS server is an auto-learning DNS,

which means that when a new computer is connected to the network the DNS

server learns its name and automatically adds it to the DNS table. Other network

users may immediately communicate with this computer using either its name or its

IP address. In addition your gateway's DNS:

 Shares a common database of domain names and IP addresses with the

DHCP server.

 Supports multiple subnets within the LAN simultaneously.

 Automatically appends a domain name to unqualified names.

 Allows new domain names to be added to the database using Watson's WBM.

 Permits a computer to have multiple host names.

 Permits a host name to have multiple IPs (needed if a host has multiple net-

work cards).

The DNS server does not require configuration. However, you may wish to view the

list of computers known by the DNS, edit the host name or IP address of a comput-

er on the list, or manually add a new computer to the list.

8.6.1.1 Viewing and Modifying the DNS Table

To view the list of computers stored in the DNS table:
