2.2 Conﬁguration of network interfaces of the Internet gateway

Note: IP addresses can be assigned to printers either manually or by a DHCP server.

If a DHCP server is used, the printing machine is conﬁgured automatically and its

address is listed in the DHCP lease list. If conﬁgured manually, the printing machine

will be independent of the DHCP server’s availability.

• Dynamic IP addresses will be assigned to local workstations (easier conﬁguration).

Figure 2.1 Example of conﬁguration of a network with assigned IP addresses

Notes:

1. The DNS domain in the LAN must be identical with the Active Directory domain (i.e.

company.com).

2. IP addresses 10.1.1.x with the subnet mask 255.255.255.0 will be used in the network

of the branch oﬃce. The Active Directory domain is not used in this network, so it is

necessary to create a local DNS domain filial.company.com.

2.2 Conﬁguration of network interfaces of the Internet gateway

Internet gateway is a host (or a server) at the boundary of LAN and the Internet. In this

example, a server with Windows will be used. The Kerio Control ﬁrewall (see chapter 2.3) as

well as Kerio Connect will be installed on this server. Kerio Connect will be used as a mailserver

and groupware server.
