The local network of the Intra2net system and the peer use an identical or at least overlapping network area. In this example it is 192.168.1.0/24.
To resolve the address conflict, the local network of the peer is rewritten to 192.168.10.0/24. If a client from the LAN of the Intra2net system wants to reach the peer, it must address the corresponding IP in the network 192.168.10.0/24 instead of 192.168.1.0/24.
At the same time, the LAN of the Intra2net system can be reached by the peer on 192.168.2.0/24.
Both address conversions take place on the Intra2net system, the peer does not participate. If an Intra2net system is used on both sides of the VPN, the address conversion may only be set on one side.
