If the Intra2net system is to be used only for limited purposes (e.g. only as an email server), it may be advisable to connect the clients within the local network using a different router. To ensure that the Intra2net system can use another router to access the Internet, although it is not addressed through the external but via the internal interface, there is the provider type "Router in the local network".

Under this configuration, the firewall has very limited functionality. There are also limitations to VPN and port forwarding.
