Network
Wi-Fi
Although dhcp will already work out of the box, Wi-Fi will not. Luckily there exists wpa_supplicant, enable it in /etc/NetworkManager/NetworkManager.conf:
[main]
dhcp=internal
plugins=ifupdown,keyfile
[ifupdown]
managed=true
[device]
wifi.scan-rand-mac-address=yes
wifi.backend=wpa_supplicant
Now restart the service, and you should be able to connect with Wi-Fi.
# rc-service networkmanager restart
There are different frontends to configure connections but for now install networkmanager-tui:
# apk add networkmanager-tui
# nmtui
It should be self-explanatory how to use it.
To make it possible for users to edit connections create the config file /etc/NetworkManager/conf.d/no-polkit.conf with:
[main]
auth-polkit=false
VPN
NetworkManager can already use WireGuard but to use other VPNs it might be necessary to install their corresponding plugin. For OpenVPN that would be:
# apk add networkmanager-openvpn
Security considerations
NetworkManager defaults are fine for normal usage but in terms of security they are definitely lacking.
MAC Randomization
Create a config file /etc/NetworkManager/conf.d/mac-rand.conf to randomize the mac address every time your computer connects:
[connection-mac-randomization]
ethernet.cloned-mac-address=random
wifi.cloned-mac-address=random
IPv6 privacy
Although ipv6 will be turned off in the security section you can still turn it on by editing /etc/NetworkManager/conf.d/ipv6-privacy.conf:
[connection]
ipv6.ip6-privacy=2
