Excuse me for the long delay.
Yes, the two WAN are on the same network: Site A 203.0.113.1/24 - Site B 203.0.113.2/24
Later i will try the advanced firewall suggested settings
Thank You

There is a switch to which they are connected.

Some details:
I've created a test environment with 2 minipc 4 nic using exactly all settings in this example:
https://docs.opnsense.org/manual/how-tos/wireguard-s2s.html
The tunnel has never been online

After days of testing i've found the only solution for a site to site VPN is PFsense.
With the latest OPNsense with every combination i've tried there's nothing to do.

I have to connect two separate building across a VPN Site to Site with 2 opnsense 25.7 installed.
Every building have a dsl connection with a public ip address and the opnsense firewall are behind the isp router with an assigned private ip address and nat 1:1 with a nat 1:1 (DMZ, exposed host) activated on the router to the wan ip address of the firewall.
I've tried IPSEC, Wireguard and OpenVPN with no success.
At the moment i'm triing again with wireguard with the official guide https://docs.opnsense.org/manual/how-tos/wireguard-s2s.html and this videoguide https://www.youtube.com/watch?v=884RX3dKeek but the peer is always offline
Someone can help me to diagnose it ?
Thedebug log is very poor and i don't see any error in.

Thank You
