Greetings,
I=E2=80=99m very new to Alpine Linux, running it under qemu as a DHCP =
and PiHole (docker) server currently.
Being familiar with Debian I installed ufw for packet filtering and =
it=E2=80=99s working well.
However, there=E2=80=99s a problematic behaviour - when starting the OS =
instance, ufw start fails with

- - - - - -
* Starting ufw =E2=80=A6
Another app is currently holding the xtables lock. Perhaps you want to =
use the -w option?
ip6tables-restore: line 2 failed
Problem running =E2=80=98/etc/ufw/before6.rules=E2=80=99
* Failed to start ufw.
* ERROR: ufw failed to start
- - - - - -

The rest appears to be working correctly, although I seem to be unable =
to ssh into the instance unless I wait=20
around 2 minutes after the startup, and without any action from my side =
(possibly unrelated).

To correct the problem, I console in into the instance and start ufw =
manually, and it works without a hitch.
So I suspect a dependency problem at startup.
I am not familiar with OpenRC but all symptoms seem to disappear when, =
in /etc/init.d/ufw, I change
=E2=80=9Cbefore net=E2=80=9D -> =E2=80=9Cafter net=E2=80=9D.

My question is:
- what is the correct dependency for the ufw init script?

Regards,
