The TCP ports 80 and 443 are NAT-forwarded by the gateway to 172.30.0.6.
This address was originally occupied by *rprx0.pyrocufflink.blue*, which
operated a reverse proxy for Bitwarden, Gitea, Jenkins, Nextcloud,
OpenVPN, and the public web sites. Now, *web0.pyrocufflink.blue* is
configured to proxy for those services that it does not directly host
itself, effectively making it a web server, a reverse proxy, and a
forward proxy (for OpenVPN only). Thus, it must take over this address
in order to receive forwarded traffic from the Internet.
