So my network topology is this:
LAN Gateway is: 192.168.2.1
RUT240 LAN IP is: 192.168.2.237
RUT240 assigns VPN dhcp IPs to connecting clients in the 192.168.255.0/24 range
My problem is that when a VPN client gets assigned IP 192.168.255.6 for example, it can't talk directly to other devices in the 192.168.2.0/24 LAN because that device doesn't know how to reach 192.168.255.0/24 and even my gateway doesn't have a route for 192.168.2.0/24.
I want to keep it this way, because I'm using the RUT240 as an OOB last-resort connection method. I have to assume everything is down, including the gateway ( imagine a power loss ). This means the RUT240 must be able to talk to devices on 192.168.2.0/24 directly, without a gateway.
I believe I have to configure the RUT240 to NAT the VPN connections to its own LAN IP ( 192.168.2.237 ) which would then allow for direct connections to the rest of the LAN.
Has anyone else done this ? Is it possible ?
