I think in this moment that i want to do its impossible. I mean.
I need to do a VPN between some smartphones, iPads and a Lan with a router in the middle. After this router with SPI is the Pfsense(OpenVPN)
The Wan port por of the router is the conection to Internet. For example 77.27.XXX.XXX/22
The network between the router and the pFsense is 192.168.0.0/30 // Port1 of the router 192.168.0.1 and Wan port of pfSense is 192.168.0.2
Port Lan of pfSense is 192.168.83.0./27
Its possible or impossible?
Sorry for my english, but i write them from Spain.
Thank you so much.
Why you don't use pfSense as router too? He's perfectly capable of that besides firewall.
Maybe I don't understand what you need?
On the front router, port forward the port/s you need for a VPN server (e.g. 1194) from 77.27.xxx.xxx:1194 to 192.168.0.2:1194 - then pfSense can be the VPN server listening at 192.168.0.2:1194 and provide access to the LAN 192.168.83.0/27
If it is more complicated than this, then post in one of the VPN forum categories including a network diagram and you'll get good help.
This is the diagram of my lab.
The pfSense is the Vpn Server with OpenVPN.
