Network Address Translation (Nat) - SMC Networks Barricade SMC7004ABR User Manual

•
LAN IP – Use the LAN menu to configure the LAN IP address
for the Barricade Router and to enable the DHCP server for
dynamic client address allocation.
•
Set a period for the lease time if required. For home networks
this may be set to Forever, which means there is no time limit
on the IP address lease.
•
IP Address Pool – A dynamic IP start address may be
specified by the user, e.g. 192.168.2.100 (default value).
Once this start IP address has been assigned, IP addresses
running from 192.168.2.100 to 192.168.2.199 will be part of
the dynamic IP address pool. IP addresses from 192.168.2.2
to 192.168.2.99, and 192.168.2.200 to 192.168.2.254 will be
available as static IP addresses.
Remember not to include the address of the Barricade Router in
the client address pool. Also remember to configure your client
PCs for dynamic IP address allocation.
