Add platform = none as the shipped default so installing the package changes nothing on the machine until a platform is chosen. Add a mode setting (manual/interfaces/auto) controlling how much of the network configuration is supplied versus detected from the system. Manage /etc/vpn-router/vpn-router.conf with ucf instead of writing it once, so dpkg-reconfigure can safely reapply debconf answers without clobbering local edits. Extend NAT/forward rules to all local subnets, not just the first.
