This option would be useful if you wanted to use a separate, physical DNS server for your internal users. A domain override allows you to specify an alternate DNS server to handle resolving DNS requests for a particular domain name. In this example, I used host overrides, but there is also domain overrides. Once you click the “Save” button, the changes will need to be applied in order for the override to take effect.

The “Description” box is optional but could be useful if you want to explain what is being overridden and why you are doing it (for your future self that may forget the rationale). In our example, that would be the local IP address of 192.168.1.10. For the “Type”, the default is correct since I am not overriding a MX record for an email server. To do so, click on the tiny “+” icon in the right hand corner of the host overrides table.Įnter the hostname, which becomes the subdomain of the web hosted service, in the box labeled “Host”. I want the to return the local IP address. You will see sections for host and domain overrides.įor the scenario I described above, the host overrides will be used because we simply want to return a different IP address for specific hosts. To add a new unbound DNS override, go to “Services > Unbound DNS > Overrides”. When performing a DNS lookup, the unbound DNS service will return the local IP address for any hostname/domain name in the list of overrides. This scenario can be easily configured in OPNsense using the default unbound DNS service. For example, the web address “” could point to a public IP address for external users since they will use the public DNS record during a DNS lookup but internal users would access a local IP address such as 192.168.1.10 when visiting “”. Split DNS allows you to use the internal IP address of a device for local users and the external IP for external users. To resolve this issue, I made use of split DNS (aka split-horizon, split-brain, or split-view DNS).

This greatly reduced the quality of streaming videos on my network and caused unnecessary transcoding of most of my videos (since I have them encoded in the mp4 format compatible with the Apple TV). Plex would treat connections from my local network as a remote connection since it was using the external WAN IP address. I encountered an issue when I used the URL that I use for external access to my server. I am using my own registered domain name which I use to refer to devices on my network (both internally and externally, which you can read more about in another article I wrote. On Plex I have limited the bandwidth remote users may use to be slightly less than the maximum of my upload speed so my home network is still usable. On my home network, I host a few public facing services that my family and I make use of when away from home such as Plex Media Server.
