Configuration Settings: Firewall Profile
5.17 IP Route
The system acts as the default gateway for its DHCP clients. It can also be specified as the default gateway
for devices with static IP addresses on the same subnet as the system. When devices want to send data to IP
addresses on different subnets, they will send that data to the system as their default gateway for onward
routing.
The IP Route table is used by the system to determine where data traffic should be forwarded. This is done
by matching details of the destination IP address to IP Route records and then using the Destination specified
by the matching IP route. These are referred to as 'static routes'.
· Automatic Routing (RIP)
The system can support RIP (Routing Information Protocol) on LAN1 and or LAN2. This is a method through which
the system can automatically learn routes for data traffic from other routers that also support matching RIP
options, see RIP . These are referred to as 'dynamic routes'. This option is not supported on Linux based
servers.
· Dynamic versus Static Routes
By default, static routes entered into the system override any dynamic routes it learns by the use of RIP. This
behavior is controlled by the Favor RIP Routes over static routes option on the System | System tab.
· Static IP Route Destinations
The system allows the following to be used as the destinations for IP routes:
· LAN1
Direct the traffic to the system's LAN1.
· LAN2
On IP Office Aura Edition systems, traffic can be directed to LAN2.
· Service
Traffic can be directed to a service. The service defines the details necessary to connect to a remote data
service.
· Tunnel
Traffic can be directed to an IPSec or L2TP tunnel.
· Default Route
The system provides two methods of defining a default route for IP traffic that does not match any other specified
routes. Use either of the following methods:
· Default Service
Within the settings for services, one service can be set as the Default Route (Service | Service ).
· Default IP Route
Create an IP Route record with a blank IP Address and blank IP Mask set to the required destination for default
traffic.
