Your OPNsense Firewall has the example IP Subnets ``203.0.113.0/24`` and ``2001:db8:1234::/48``. The FQDN can point to any bindable IPv4 and IPv6 address in those subnets. It will be used by clients to connect to the IPsec VPN Server - and by the OPNsense to bind the local listen address.
- Create an A-Record with your external DNS provider, for example ``vpn1.example.com in A 203.0.113.1``
- *Optional:*Create an AAAA-Record Record, for example ``vpn1.example.com in AAAA 2001:db8:1234::1``
- Create an AAAA-Record, for example ``vpn1.example.com in AAAA 2001:db8:1234::1``
