3. CONFIGURATION
Continued from previous page
Item
Description
Default Gateway
Specifies the IP address of default gateway. When entering the IP
address of default gateway, every packet 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 forwards an IP address requests to
the DNS server.
Table 14: Configuration of the Network Interface
The router considers the last address in the network range to be broadcast address,
regardless of the address is set as a broadcast or not. Connection (ping) to the broadcast
address does not work.
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
). 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.
