I got the configuration of the connection to the main office of the company via ipsec. I configured phase 1 and phase 2 but in the logs I see that I can't connect. No response from the remote server. I have created firewall rules, I don't know if they are ok. But I'm afraid that my gateway is blocking something.
Where did you set up the IPSec? On OPNsene or on a device behind it?
Is it a site to site or client to site VPN?
If you run it on OPNsense itself please post the log.
