UDgateway - Hardware Guide
UDgateway Installation
Connections
3.4.2.
All connectors are on the rear side of the UDgateway®. Connect all cables according
to the cabling plan below.
Ethernet connections
3.4.2.1.
-
xl0 (WAN)
- This interface must be connected to the Constraint Network.
-
fxp0 (LAN)
- This interface must be used for initial configuration (step-by-step
configuration)
Traffic going through fxp0 interface is intercepted in order to be optimized when
going through xl0 interface.
-
xl1 (WAN1)
- This interface is used in a multi-WAN environment with Link
Management option.
-
xl2 (WAN2)
- This interface is used in a multi-WAN environment with Link
Management option.

Remark
: A constraint Network is a network with long delays and bandwidth
limitations which requires optimization.
It is highly recommended that fxp0 and xl0 interfaces are connected to different
Ethernet switches. If the same Ethernet switch is used, fxp0 and xl0 Ethernet segment
should be isolated using VLAN technology.
