2.6 DNS conﬁguration

this example the 192.168.1.3 address is reserved). You need to know the hardware (MAC)

address of the printing machine to make the reservation.

Hint

Do not make the reservation manually unless you know the MAC address of your printing

machine. Run the DHCP server and connect the machine to the network. An IP address from

the formerly deﬁned scope (see above) will be assigned to the printing machine. In the list

of leased addresses, mark this IP address and click on Reserve.... This opens a dialog for IP

address reservation with the corresponding MAC address already predeﬁned. Change reserved

IP address to the desired one (192.168.1.3), edit the description and click on OK. Restart your

printing machine. The appropriate IP address will be assigned to the printing machine by the

DHCP server after the restart.

Notes:

1. Do not enable (allow) the DHCP server unless all desired scopes and reservations are made

or unless you need to determine a client’s MAC address (see above).

2. You can also use another DHCP server to detect settings of your network equipment au-

tomatically. Set the ﬁrewall computer’s internal IP address (192.168.1.1) as the default

gateway and DNS server in parameters for this range on the DHCP server.

2.6 DNS conﬁguration

In Conﬁguration → DNS, keep the default settings (the DNS forwarder service and simple

DNS translation woth the hosts ﬁle and a table of leased addresses are allowed) and set the

advanced options:

• Enter the local DNS domain name — company.com.

• Enable the Use custom forwarding option Add the rule for forwarding of requests to

the Active Directory, i.e. of all requests for names starting with _ (underscore), to the

domain server in the LAN. This setting is required for correct communication of local

computers with the domain server.

Table 2.1 Rule for forwarding of DNS requests to Active Directory

It is also necessary to add rules for correct forwarding of DNS queries between the

headquarters’ network and networks of branch oﬃces. For detailed description on

these settings, refer to chapters 4.1 and 4.2.
