How to make OpenVPN Client use DNS Resolver?

[testcb00]

Hi everyone,

I have made a OpenVPN Server in pfSense and I can connect to my private Nextcloud using IP Address in my OpenVPN Client.

However, I find that I cannot use nextcloud.mydomain to connect my Nextcloud.

I add the OpenVPN Local Network (10.10.10.0/24) to the DNS Resolver Access Lists but no luck.

The current DNS Resolver settings are

Network Interfaces
#---------------------------
LAN
VPN
Localhost

Outgoing Network Interfaces
#---------------------------
WAN

System Domain Local Zone Type
#---------------------------
Static

DNSSEC
#---------------------------
✓ Enable DNSSEC Support

Python Module
#---------------------------
□ Enable Python Module

DNS Query Forwarding
#---------------------------
□ Enable Forwarding Mode
□ Use SSL/TLS for outgoing DNS Queries to Forwarding Servers

DHCP Registration
#---------------------------
✓ Register DHCP leases in the DNS Resolver

Static DHCP
#---------------------------
✓ Register DHCP static mappings in the DNS Resolver

OpenVPN Clients
#---------------------------
✓ Register connected OpenVPN clients in the DNS Resolver

Host Overrides
#---------------------------
nextcloud mydomain 192.168.160.101

@testcb00 You have to put in a pfSense IP in the OVPN Server in the DNS field, take the IP of the OVPN Server itself is probably a good idea.

@bob-dig Thank for your reply.

Currently my OpenVPN settings is here

In the above photo, 192.168.160.0/24 IPv4 Local network which OpenVPN Client can access.
With this setting, I can connect to Nextcloud using nextcloud.mydomain now
