9. Chapter - Intranet

9.1. IPs and Networks

Under Network > Interfaces the system's network cards can be configured.

The following types/modes can be selected for the network cards:

LAN with NATLocal network. When accessing the Internet, the local IP addresses are converted to the Internet IP of the Intra2net system (network address translation, NAT). This is the default configuration for local networks.
LAN without NATLocal network. No NAT is used when accessing the Internet. Use this mode for a DMZ (Demilitarized Zone) with official IPs or if the Intra2net system does not provide direct access to the Internet and another router is responsible for NAT.
DSL/RouterNetwork card used to route access to the Internet. Either via a DSL modem or a router. Which one of them is used is dependent on the type of provider profile used. The provider type and IPs are not set here, but under Network > Provider > Profiles.
Proxy ARPLocal network without NAT using IPs from the router range. A detailed description can be found at Section 11.7.3, „Proxy-ARP“.
unusednot active.

A firewall profile can be assigned to the LAN network cards. This is then valid for all IPs on this network, for which no more specific configuration (e.g. by entering as client or network range) has to be made. Further details are given under Section 9.3, “Access Rights of a Network Object”.
