Subject: wg set fail to update endpoint if traffic is flowing
Date: Tue, 31 Mar 2020 08:36:52 +0000
Message-ID: <i2UwKoKpd7CcDmlKuf5GHwFTjVhsyWaKbbI_QaLQ5yjGbpBkH7klwefEhR8B7TICn7B4uguk3sK23sExHYpQFUX9txdU-RDQR7w0bCuNj4E=@nexmanti.net> (raw)

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
