The main task of the DNS server is to distinguish requests for names in the Internet
from those for other remote stations. Therefore, enter all computers into the DNS
table
– for which you know the name and IP address,
– that are not located in your own LAN,
– that are not on the Internet and
– that are accessible via the router.
For example, if would like to access the mail server at your headquarters (name:
mail.yourdomain.com, IP: 10.0.0.99) via the router from a branch office, enter:
cd setup/DNS-module/DNS-table
set mail.yourdomain.com 10.0.0.99
Stating the domain is optional but recommended.
When you now start your mail program, it will probably automatically look for the
server 'mail.yourdomain.com'. The DNS server thereupon returns the IP address
'10.0.0.99'. The mail program will then look for that IP address. With the proper
entries in the IP routing table and name list, a connection is automatically
established to the network in the headquarters, and finally to the mail server.
