natpmpc may be available in alpine

[JohannesBe]

Hi there!

I believe the natpmpc command is actually available in alpine linux: https://pkgs.alpinelinux.org/contents?branch=edge&name=libnatpmp&arch=armv7&repo=community

So this part of the documentation is technically correct (as in, you couldn't find it), but it may be misleading to some people:

Well, as far as I could find, Alpine Linux doesn't have natively the binary for natpmpc, the NAT-PMP client used to request the port forward as per the instructions for manual mapping on ProtonVPN. Gluetun is using alpine as it's base image.

So maybe, it'd be nice if you could include an UPDATE somewhere or so.

It might then also be useful to provide your script as an extension of gluetun (i.e. FROM gluetun , ADD start.sh , ...). That way no sharing of the docker socket is needed (usually considered a security risk).

Don't feel obliged in any way to do something with this information though, I just thought you'd maybe want to know ;)

Kind regards, J
