o Netmask --
Enter the Netmask for the above IP Network e.g. for
the 10.10.10.0 a class C subnet mask would be 255.255.255.0 with
254 host, a class B subnet mask would be 255.255.0.0 with 65,534
host, a class A subnet mask would be 255.0.0.0 with 16,777,214
hosts.
o Gateway --
Enter the IP gateway for this IP Network, typically this
will be a router on the same IP subnet as the systems LAN interface, if
the systems IP address is 192.168.1.1 and there is a router on this
subnet that has an IP address of 192.168.1.254, that is routing traffic
to 10.10.10.0 subnet, make this router the Gateway for this IP
Network.

Select Submit
Note; To delete the Route enter the data as the route appears
below, then de-select the Apply Route and click Submit.
VoIP Subnet Routing
In its simplest configuration, the system acts as a proxy for network devices
on its own subnet. Because the network devices reside on the same subnet as
the system, packets proxied by the ALG function and sent to the LAN require
no additional routing information.
Sometimes the system is placed on a subnet that is separate from the
subnet(s) of the VoIP networking devices it serves. These subnets reach the
system via intermediate routers. The intermediate routers are configured to
direct data from network devices to the system. In order for the system to
send RTP media data to the intermediate router, a return path must be
configured on the system.
Using the VoIP Subnet Routing feature, the system can be configured to serve
these remote VoIP networking devices.
Note; To system is limited to a total of 20 VoIP subnets
⇒
Select System --
Select VoIP Subnet Routing --
Allow ALG routing of
VoIP data for multiple subnets.
o IP Network --
Enter the IPv4 network address e.g 10.10.10.0 will
define the entire subnet with all 254 hosts.
o Netmask --
Enter the Netmask for the above IP Network e.g. for
the 10.10.10.0 a class C subnet mask would be 255.255.255.0 with
254 host, a class B subnet mask would be 255.255.0.0 with 65,534
