IPSEC site to site connection- PFsense

Hello Everyone,

I am a student of Networking and System Security, and I'm trying to establish a connection between a Ubuntu Client and a webserver on different lans.

PC1 on LAN1 has to connect to Webserver2 on LAN2 PC2 on LAN2 has to connect to Webserver1 on LAN1

They are all in the same WAN network

All encrypton parameters and other stuff are the same. I've managed to connect PC1 to PC2 but not with webservers.

I've been struggling with this for a few days so I had to come to reddit hoping for a shed of light.

Thank you for any help.
