@Dwreck_Herndon,

Regarding OneMesh configurations, it seems that no models have been released with this feature yet. However, we are currently updating our REs and Routers to support EasyMesh, which enables router-router connections to create a mesh network. This update is being rolled out to models through firmware updates. Additionally, we have observed that the ethernet backhaul for EasyMesh networks is already being introduced to Archers.

Unfortunately, I don't have any experience with the features and requirements of opnsense, so there may be ways to configure the connection using Static Routes or a VPN Passthroughs; but I am not sure.

In general, OneMesh and EasyMesh work relatively the same. OneMesh is simply TP-Link's mesh feature that has been out a few years, while EasyMesh can be used with compatible EasyMesh devices from other manufactures, and is only just starting to gain traction. You can see more about the differences between the two and how the feature can be used in this article.this article.

For an EasyMesh network to be created, the devices have to be in router mode and the main router must support EasyMesh. It is also worth mentioning that the ethernet backhaul is not a given when seeing EasyMesh compatibility. This functionality is still being developed and has only rolled out to some of the newest REs and some Routers. The patch notes for firmware updates will indicate specifically if the wired backhaul feature has been implemented.

  @Virus2500,

And yes the main router must support EasyMesh. You may be able to find other users who have found ways of adding EasyMesh to an opnsense device as it is meant to work with any manufacturer. I am just not sure how well supported EasyMesh is at an OpenSource level or if it is reserved for manufacturers to implement.

Not so much as Planned, as it is being Actively Developed and Rolled Out to Models that they can develop the feature for. 

I am sure that as an industry-wide protocol, there are requirements that must be met to guarantee stability and security, so it will most likely not make it to each and every model. Unfortunately, we don't have a list of models that they are planning on developing the feature for; however, the rollout is only just starting. Your best bet is to watch the patch notes for new firmware as it will show something similar to this:

  @Virus2500,

I can forward your request to our team to potentially add it as an advanced configuration option; but I do not believe this is a bug, and is moreso the intended design.

Changing the DNS setting of an AP has been rarely used at a consumer level, and is, unfortunately, more likely to cause problems for the majority of users. Before, this was never really a problem, but we are only now beginning to see extra network hardware that operates on your local network and requires settings such as this to be changed. Given how many of these devices and services we are seeing, it may be considered for future updates.
