Hi there! I have a couple of error messages that are printing constantly in my syslog that I'm not sure what to do about. Reporting here in case it's a bug, please let me know if I should post this somewhere else. I'm running version 2.2.1 on Debian Buster (compiled from source with "--igd2 --ipv6 --vendorcfg --pcp-peer --portinuse --firewall=nftables").

I turned up debug logging to get more information. Would love any help you can provide!

Here is the first one. It appears to come from my Macbook:

Code:

...and this one seems to come from a number of linux hosts on my network:

Ah, I think the first one is this:
https://github.com/tailscale/tailscale/issues/810

Looks like it should go away once my Macbook gets the latest tailscale version.

Actually I think both of these are tailscale. Filed another issue here:

well it could be there is indeed no PCP mapping / pinhole matching...
Can you list the nftables contents ?

I'm sorry, I actually re-compiled without --igd2, so I'm not seeing this anymore.
