DHCP configuration
•
DHCP
Dynamic Host Configuration Protocol; a protocol used by
client devices that are connected to the LAN port of this
device to automatically obtain an IP address assigned by
this device. Selecting Enable will configure this device to
assign IP addresses to client devices taken from a pool
specified by the values entered in DHCP start range and
DHCP end range. Selecting Disable will turn off this DHCP
server functionality
•
DHCP start range
DHCP server starting IP address. The default is set as
192.168.1.120
•
DHCP end range
DHCP server ending IP address. The maximum usable
number is 253. The default is set to 192.168.1.200
•
DHCP lease time
Sets the duration, in seconds, the connected device is
allowed to keep the assigned IP address. In many cases it
is possible for the device to receive the same IP address
after the lease time expires. The default is set to 86400
seconds (1 day)
•
Sequential IP
IP addresses are allocated sequentially from the start-end
range when checked. Addresses are based on the device’s
hashed MAC address when unchecked – this will tend to
allocate the device the same IP address when connected
to different 645M routers. Note: This setting affects WLAN
DHCP also
3.3 Router

3.3.1 Port forwards
Port Forwarding is a technique for transmitting and receiving
network traffic through a router that involves re-writing the
destination IP addresses and optionally the TCP/UDP port
numbers of IP packets as they pass through. The various
routing configurations will be displayed in the IP Forwarding
Configuration Table at the bottom of the Port Forwards page.
