# Alpine 3.19 replaced legacy iptables with nftables based implementation.

# Tailscale is used on some hosts that don't support nftables, such as Synology
|
|
# NAS, so link iptables back to legacy version. Hosts that don't require legacy
|
|
# iptables should be able to use Tailscale in nftables mode. See
