Continued from previous page

Item Description

PoE PSE

• enabled – The router provides power on the Ethernet cable.

• disabled – The router does not provide power on the Ethernet

cable (default).

Default Gateway Speciﬁes the IP address of default gateway. When entering the IP

address of default gateway, every pac ket for which the destination IP

address was not found in the routing table, is sent to this IP address.

DNS server Speciﬁes the IP address of the DNS server. When the IP address is not

found the Routing Table, the router for wards an IP address requests to

the DNS server.

Table 15: Conﬁguration of the Network Interface

The Default Gateway and DNS Server items are only used if the DHCP Client item is set

to disabled and if the Primary or Secondary LAN is selected by the Backup Routes system

as the default route. (The selection algorithm is described in section 4.7). Since FW 5.3.0,

Default Gateway and DNS Server are also supported on bridged interfaces (e.g. eth0 + eth1).

Only one bridge can be active on the router. The Only DHCP Client, IP Address and Subnet

Mask parameters are used to conﬁgure the bridge. Primary LAN has higher priority when both

interfaces (eth0, eth1) are added to the bridge. Other interfaces (wlan0 – wiﬁ) can be added to

or deleted from an existing bridge at any time. The bridge can be created on demand for such

interfaces, but not if it is conﬁgured by their respective parameters.

The DHCP server assigns the IP address, gateway IP address (IP address of the router)

and IP address of the DNS server (IP address of the router) to the connected clients. If these

values are ﬁlled in by the user in the conﬁguration form, they will be preferred.

The DHCP server supports static and dynamic assignment of IP addresses. Dynamic

DHCP assigns clients IP addresses from a deﬁned address space. Static DHCP assigns IP

addresses that correspond to the MAC addresses of connected clients.
