Network Setup > Masquerading
Small Office Example
Create a private network just for the dial-in users and then masquerade it to the MultiAccess
Solution:
interface that is on your LAN.
This example is based on the premise the MultiAccess is a 24-port server, full or near full capacity is expected
to be reached on a regular basis and most dial-in users only require a dynamic IP address. This means the IP
address pool for the dial-up connections should be a contiguous group of 24. The users that receive IP
addresses from this masqueraded pool will appear on the network with their source address being the same as
that of the MultiAccess.
For example, the IP address of Ethernet 1 is 192.168.4.235 with a subnetmask of 255.255.255.000 and the
network's default gateway is 192.168.4.1. These addresses are set in the Network Setup menu.
Next, create a private network in Network and Services > Networks menu of 192.168.5.000 with a subnetmask
of 255.255.255.000; give it an arbitrary yet meaningful name, like dialup or modempool.
Then, masquerade this network to Ethernet 1 using the Network Setup > Masquerading menu by selecting the
Network and masquerade it to Ethernet 1 (ehto0) and then click add.
IP addresses assigned to the dial-up users are configured in the User Authentication > Radius Client
Note:
menu. For this case, the Remote Host IP address field in the Radius Client menu would have to be
192.168.5.1+, that is, the plus means pool and the .1 is the starting host address.
