Hi @yakovlev.alexey.n , how it possible to reproduce on the our LAB? Can you describe this moment if you know?

Ok, thanks, will mark as resolved.

@Harunaga did you test the latest version? https://phabricator.accel-ppp.org/R1:d8c4209188481c3836d87266f5cc6e37661df8fd

I propose update accel-ppp.conf.5 for the actual state if something is missing
About https://accel-ppp.readthedocs.io/, we can also migrate this to the self-hosted side when appears some access issues.
Main goal docs on readthedocs.io to provide guides and detailed instruction instead of accel-ppp.conf.5

@faceless fixed in organization repository https://github.com/accel-ppp/accel-ppp.git

Note: The main reason - for last Requests accel-ppp answer to client MAC address instead of Relay MAC address.
