Even if your network does not use RIP or RIP2 dynamic routing, the Ethernet TAP probe can still communicate across routers and gateways if you enter a default gateway or a full routing table into flash memory.
If you are using a static IP configuration or your DHCP configuration does not specify a default gateway, you can manually enter the IP address of the default gateway to use. This gateway must be accessible on your local subnet.
A default gateway entry must specify the IP address of the first gateway that the network traffic from probe crosses. This gateway must be aware of the network's complete route table. Use the following netparam syntax:
netparam add_route 0.0.0.0 gateway_ip 1
For gateway_ip, provide the IP address of the router or gateway in dot notation. The default value is 0.0.0.0.
