Dealing with Home Users Using VPN with the Same Subnet: : msp

Hi I am setting up a VPN between my client and their owner, in order for the owner to access ressources at my clients site. Unfortunatly their owner already has an VPN connection to another site with the same subnet as the one on my clients site. I have setup a policy NAT to translate my clients in Solved: Site-to-Site VPN tunnel with same local - Cisco On our side, local subnet 192.168.144.0/24 have to be connected to 192.168.90.0/24 on their side. No problems so far. However, Aside from the 90 subnet, our client also has another internal subnet which is the exact same 192.168.144.0/24 subnet. So this is gonna be an issue and simply setting up the VPN tunnel is not gonna work. windows - VPN with same IP ranges - Super User If the VPN is using the same subnet range as your local LAN, then the easiest fix would probably be to either change the VPN subnet or the LAN subnet (I use 192.168.0.0/24 and 192.168.1.0/24, for example).. If you only need to use say one or two devices on the remote network, you can just set up static routes for those devices and remove the VPN's subnet route:

Azure reserves the first and last address in each subnet for protocol conformance. Three additional addresses are reserved for Azure service usage. As a result, defining a subnet with a /29 address range results in three usable IP addresses in the subnet. If you plan to connect a virtual network to a VPN gateway, you must create a gateway subnet.

If your VPN setup is over a wireless network, where all clients and the server are on the same wireless subnet, add the local flag: push "redirect-gateway local def1" Pushing the redirect-gateway option to clients will cause all IP network traffic originating on client machines to pass through the OpenVPN server.
