We are establishing a host-to-host VPN with our business partner. After we exchanged our IP information they said that our LAN IP range will overlap their LAN IP range and we had to do an internal NAT.
Our current LAN is
192.168.0.1/24 and we need to NAT this range to
192.168.2.27 in order to establish the tunnel.
Our network infrastructure is very simple. We have an optical fiber modem connected to our Cisco RV325 router (WAN port). Our router is connected to an unmanaged switch in it's LAN port.
The Cisco RV325 is the device that will establish the VPN tunnel and do all our LAN work (Gateway, DHCP Server).
I'm not familiar with NATing so I'm not sure if our RV325 can do that internal NAT before establishing the tunnel.
I'll be very grateful if anyone is willing to shed some light or share some advice.
