For example, you may define that a LAN ethernet connection on OpenRG will operate as a WAN network. This means that all hosts in this LAN will be referred to as WAN computers, both by computers outside OpenRG and by OpenRG itself. WAN and firewall rules may be applied, such as on any other WAN network.
Another example, is that a network connection can be defined as a DMZ (Demilitarized) network. Although the network is physically inside OpenRG, it will function as an unsecured, independent network, for which OpenRG merely acts as a router.
One of these three network types is defined in each connection's configuration screen, in the 'Network' combo-box, as depicted in the following sections.
