Wand and lan on the same subnet

[k13tas]

Hello,

I want to set up pfSense for vpn.
I do not have a public IP address to use for pfSense WAN interface.
Instead my ISP has forwarded all needed ports to one specific IP address on my LAN network (192.168.50.100). I want to use this IP address on my WAN interface and 192.168.50.0/24 on my LAN interface. pfSense gives me an error saying that this IP address is already being used on WAN interface. Is there something I can do about it?

Right.

Use 192.168.50.100 on WAN and 192.168.51.0/24 on LAN.

That is a fundamental concept of how routers work.

Thank you for answering.
I guess I'll have to ask my ISP to setup something like that since I don't control any of our routers myself.

Sorry to hear that.

Just change your lan network to something else and put everything behind pfsense..

so

internet - isp router –- 192.168.50/x --- 192.168.50.100 pfsense 192.168.51/24 -- lan (your network machines)

Which direction are you using the VPN?  If incoming, to access your network, you'll need a public IP address.
