Advanced > Routing
Routing Tables allow you to determine which physical interface address to
use for outgoing IP data grams. If you have more than one routers and
subnets, you will need to enable routing table to allow packets to find proper
routing path and allow different subnets to communicate with each other.
Dynamic Routing
Static Routing
Dynamic Routing Settings allow the VPN Router to route IP
packets to another network automatically. The RIP protocol
is applied, and broadcasts the routing information to other
routers on the network regularly.
By default, it is set to disable. Check to enable (RIPv1 / RIPv2)
protocol.
Static routing settings allow the VPN Router to route IP packets
to another network. The routing table sorts the routing
information so that your network device knows where to
redirect the IP packets to the proper network.
By default, it is set to disable. To change this configuration,
select enable.
