WebRTC not connecting between nodes

[Sepero]

I connected 2 nodes over anywherelan, and attempted to share screen using WebRTC, and a connection could not be made. Any suggestions on whether it's possible?
TLDR;

1. I put the arm version of awl on my jetkvm (ipkvm device). Made it executable.
2. I did modprobe tun and awl was able to start running immediately (to my pleasant surprise).
3. I connected/paired the jetkvm node to a couple other devices.
4. Jetkvm uses http and WebRTC as display for remote connection. So I connected to the http interface via awl 10.66.0.X
5. Despite trying to connect from two separate machines the WebRTC connection could not be established.

I tried several times and double checked browser settings, but nothing I did could get the WebRTC to finalize the connection.

Is this problem surmountable? How might I succeed in establishing connection?

Note: I do not have this issue when devices are physically on the same lan and connect together 192.168.1.X

My first guess is that it's because awl has NAT inside, which rewrites a device's IP address to the one assigned to it. This means that every device thinks it is 10.66.0.1, but this is not true for other devices.

However, after consulting with LLM, he thinks the issue could be in a broken mDNS (which I think is indeed broken).

Either way, could you please open a website with WebRTC and check either chrome://webrtc-internals/ or about:config for Firefox? Look up your session and open the Stats Tables or Candidate Table, and show me a screenshot.

If you see an address like e54a7b2e-3c4d-4f5e-9a1b-2c3d4e5f6a7b.local, you can temporarily disable mDNS for WebRTC and try again.

Chrome: chrome://flags/#enable-webrtc-hide-local-ips-with-mdns --> Disabled, then restart the browser.
Firefox: about:config --> media.peerconnection.ice.obfuscate_host_addresses --> false, then restart the browser.
