PLANET BM-2101 - Manual (Page 20)

Alias IP of Interface/Netmask
„ The multiple subnet segment range.
NAT Mode
„ Allow the internal network to set up multiple subnet addresses and connect to
network via different WAN IP addresses. For example , the company applies
several real IP addresses 168.85.88.0/24 for its lease line, and the company is
divided into R&D, Customerr Service, Sales, Procurement, Accounting
Department. For easy management, assignate different IP segment for each
department. The settings are as the following
R&D Dep. 192.168.1.1/24(Internal) ÅÆ 168.85.88.253(External)
Custermor Service Dep. 192.168.2.1/24(Internal) ÅÆ 168.85.88.252(External)
Sales Dep. 192.168.3.1/24(Internal) ÅÆ 168.85.88.251(External)
Procurement Dep. 192.168.4.1/24(Internal) ÅÆ 168.85.88.250(External)
Accounting Dep. 192.168.5.1/24(Internal) ÅÆ 168.85.88.249(External)
R&D Dep. has already been set up in Interface configurations, so set up the
reserveing four departments by adding 4 new Multiple Subnets . After completing
the settings, every department can connect to network via its own WAN IP address.
The settings of each department are as the following
Customer
Service
Sales Procurement Accounting
IP Address 192.168.2.2~254 192.168.3.2~254 192.168.4.2~254 192.168.5.2~254
Netmask 255.255.255.0 255.255.255.0 255.255.255.0 255.255.255.0
Default
Gateway 192.168.2.1 192.168.3.1 192.168.4.1 192.168.5.1
Routing Mode
„ It is almost the same as NAT mode but does not have to correspond to the real
WAN IP address, which let internal PC to access the network by its own IP.
(External user can use the IP to connect to the network)
