4.4 Configuring WAN2 Ports (optional)
WHG-505 also supports a second WAN port, called WAN2. The second port is for connecting to a second feeding
pipe upstream. When WAN1 is connected to an ISP and WAN2 is connected to another ISP, the network is referred
as 'dual ISP homing', or 'having dual homed Internet feed'. That is when the first ISP via WAN1 is down, the second
ISP via WAN2 still be able to service the client devices downstream of WHG-505.
When WAN2 is enabled, the system can be set up to support more features, such as WAN Failover and Load
Balance (but not a necessity). These two features will discuss in the next section (Other WAN traffic Settings).
By default, all Policies of WHG-505 use WAN1 as the outgoing gateway; that is, all user groups'
traffic will use WAN1 as the Internet feed. Administrator can change the Routing Profile of a Policy to
use WAN2 as default gateway; that way, for the groups bounded by the Policy will use WAN2 as
Note:
their Internet feed.
If dynamic "WAN Load Balancing" feature is not turned on, using the Policy's Routing Profile to route
some users' traffics to WAN2 is considered a way of doing static "Load Balancing".
The configuration of WAN2 is similar to WAN1's, except that WAN2 connection can be disabled and WAN2's
connection type does not have the PPTP choice.
If you only have one Internet feed from one ISP, please leave the WAN2 at its default option - None, so the WAN2
interface remains disable. If you want to use a second Internet feed (from an ISP or from your corporate
headquarter), select one of the three connection types for your WAN2 port: Static, Dynamic, and PPPoE.
Now, let us enable and configure WAN2 port (optional):
Go to: System >> WAN2
None: The WAN2 Port is disabled.
Static: Manually specifying the IP address of the WAN port. The red asterisks indicate required fields to be filled
in.
