Apparently Bitcoin Core was leaking the clearnet IP address to the peers of Tor/I2P nodes?!
That's pretty bad...

Oooough š¤¦āāļø
We need to have some VPN settings to outside on clearnet. Tor is good but vpn is more easy I suppose. #TeamMullvad
I think this bug would still have leaked your IP even if you had a VPN for the whole computer.
If you have IP forwarding they will see the IP VPN, not yours. As we do for vpn torrenting
With a vpn you are entrusting your privacy to a third party, it will never be a good option.
Yes you are right but you could use a vps backend with zerotier or wiregard. Or use a nolog vpn as mullvad.
Is Zerotier materially better?
My first exposure to ZeroTier was as a Raspiblitz plugin. Iām too in the weeds on other things to really dig into it. Choosing to run over TOR in absence of wanting to take on yet another tech service provider. But Iām genuinely curious what others have experienced?
The issue description doesn't clearly say who this affects. Does it affect nodes running as `--toronly`? Does the issue only affect nodes advertising on Tor and clearnet?
I presume nodes running in a container or VM are safe because they would likely have a different IP than given from ISP.
I'm not entirely sure, but from what I understand it also affects --toronly nodes too...

Wow! OK. I'm glad it is being fixed. I had no idea something like that was happening.
