My partner and I have set up our own netmaker coordination servers on our own VPSs and have each spent the entire day now trying to just get devices to ping anything other than our coordination servers. We can ping between two of his machines which are already connected via. RDP, but no more. Nothing handshakes, nothing replies, we've tried reinstalling and using the aforementioned iptables command. No dice. Ready to throw in the towel here and settle on netbird for our uses unless anyone here has anything else we should try
