IP Forwarding

IP Forwarding is also know as routing. It is the ability of an operating system to accept an incoming network packet, recognize it is has a destination other than itself, and forward it along to that destination. Almost all linux systems have this functionality included by default. For instance, here are steps for enabling IP forwarding on Ubuntu.. There are different IP forwarding algorithms and typically take into account the size of the packet, header information, and network information such link distances.

When running a server acting as a router in a cloud you often must disable Source/Destination Check. This allows the server to act as a router and forward traffic along. If VNS3 is acting as a router, it must have this check disabled.
