Describe the problem

Both A and B machine have ipv6 addresses, they can be connected fast via ipv6 (ping test less than 40ms)
However slow network speed connect to each other via netbird virtual address.

icmp_seq=1 ttl=64 time=109 ms

To Reproduce
A and B computer are linux
Both of them are set "DisableIPv6Discovery" to false

Expected behavior

ping test shoud be fast, e.g. less than 50ms

Are you using NetBird Cloud?

NetBird version

B is 0.28.9

NetBird status -dA output:
