Hi @EnricoCostella

To assist you better, could you please share a few more details about your setup?

1. Could you describe the specific Site-to-Site VPN scenario you’re aiming to achieve?
2. What firewall models are you using on each end of the VPN connection?

Hi @EnricoCostella

Could you please let us know if both of your firewalls are directly connected to the internet or if they are behind NAT?

Additionally, could you enable HTTPS WAN access for us to remotely access both firewalls? This would allow us to quickly review your current configuration and logs. If possible, please share the login credentials with us via private message.
