Hi,
I was trying to update dynamically the endpoint for an interface, using `reresolve-dns.sh` or something like the following:
# wg set <interface> peer "<publickey>" endpoint "<FQDN>:<port>"
But the endpoint did not change, even if the `wg set` returns successfully, with retcode `0`.
Changing something like `persistent-keepalive` does work.
I debugged a bit, and I saw that if traffic is flowing throw the wireguard interface, then the endpoint change via `wg set` does not take effect.
The set endpoint works only if no traffic is flowing.
Is this expected behavior?
Thanks,
xtus
