Pfsense can't resolve ca.vpn.airdns.org

[jaskerx 0]

Set up the connection using the airvpn pfsense how to, but I also included opendns which I have now had to remove due to other issues. Tried to restart my openvpn connection last night and for some reason it would not resolve ca.vpn.airdns.org using the normal 10.4.0.1 dns server (also doesn't seem to use my isp's). I had to enter an alternate dns server (quad9) just to get it to connect but it leaks dns now. I just would like to know why its doing this and if I might be able to avoid this in the future by using the ip address rather than the web address ca.vpn.airdns.org?

10.4.0.1 is only accessible through the VPN tunnel.

 

It's best to just pick a server and use its IP address.

Does ca.vpn.airdns.org IP ever change?

It will resolve to whatever server in Canada is least busy at the time.  So, it does change.

Is this where it might be useful to use host or domain overrides to query a different dns server? That way I can just leave 10.4.0.1 under general settings dns, and then under dns resolver host/domain overrides I tell it when looking up this domain use custom dns server?

I've never done that but sounds like it'll work.
