Docker-based gateways won't have working IPv6 (good point @AndrewDryga), so I started testing the systemd gateways more and found some issues I fixed. * Update default tab order for Deploy gateways page to prefer systemd * Update unit file to run gateway as unprivileged user * Remove dependency on `wget` in unit file * Fix iptables logic so rules as re-created on reboot * Use `/var/lib/firezone` instead of `/etc/firezone` for writing runtime files (`/etc/` is often mounted read-only on hardened systems) --------- Signed-off-by: Jamil <jamilbk@users.noreply.github.com> Co-authored-by: Andrew Dryga <andrew@dryga.com>
