Configuring Two IP Gateways on a Wide Area Network (WAN)
Configuring Two IP Gateways on a Wide Area Network (WAN)
This section describes how to configure two Model 6300’s to operate over two different
subnets of a Wide Area Network (WAN). This also applies to using the Model 6300
between two sites interconnected by the Internet.
In a WAN or Internet configuration, there is typically a router, access point or firewall
between the WAN and the Local Area Network (LAN). The following figure shows a
diagram of a typical scenario.
Given the WAN above, here is how you would configure the RoIP Gateway parameters
to allow Link 1 of the Model 6300 #1 to be paired with Link 1 of the Model 6300 #2.
System Parameters for Model 6300 #1:
• IP Address: 192.168.0.133. Usually the first three fields of the IP address
(192.168.0) must match the first three fields of the LAN IP Address of
Router/Firewall #1. The last field must be unique and not used by any other
device within LAN Subnet #1.
• Netmask: 255.255.255.0. Most local area networks have less than 256 devices
within their subnet (i.e. Class C) and therefore almost always use a net mask of
255.255.255.0.
• IP Gateway: 192.168.0.1. This must match the LAN IP address of
Router/Firewall #1.
• DNS Server IP Address: 123.213.231.30. This is only needed if an IP Send
Address in the Link Parameter Configuration pages use a URL rather than an IP
address. If used, this must match the WAN IP address of the DNS Server
otherwise this field should be left blank. See note.
