Original GitHub issue: https://github.com/netbirdio/netbird/issues/3211

Describe the problem

Both A and B mechines have ipv6, they can be ping direclty from each other with low latency.
After install netbird 0.35.2 or newer version, and netbird status show they are in p2p connection, However, their latency becomes much higher via netbird virtual ips.

Expected behavior

They should have the same latency as ipv6 direct connections.

Are you using NetBird Cloud?

yes

NetBird version

0.36.3

NetBird status -dA output:

NetBird IP: 100.83.42.2

Hey @jjqtony!

Could you provide more specific details about the latency values you're seeing?

Also, the full status output would be beneficial since it contains important information like OS and userspace mode that could help diagnose the issue.

I have found the reason. My local mechine has multiple ipv6 address. The latencies of ping some of them from vps are higher than others.
