+Listening IP
+------------
+
+By setting `LISTEN_IP` in `/etc/default/pveproxy` you can control to which IP
+address the `pveproxy` and `spiceproxy` daemons bind. The IP-address needs to
+be configured on the system.
+
+This can be used to listen only to an internal interface and thus have less
+exposure to the public internet:
+
+----
+LISTEN_IP="192.0.2.1"
+----
+
+Similarly, you can also set an IPv6 address:
+
+----
+LISTEN_IP="2001:db8:85a3::1"
+----
+
+Note that if you want to specify a link-local IPv6 address, you need to provide
+the interface name itself. For example:
+
+----
+LISTEN_IP="fe80::c463:8cff:feb9:6a4e%vmbr0"
+----
+
+WARNING: The nodes in a cluster need access to `pveproxy` for communication,
+possibly on different sub-nets. It is **not recommended** to set `LISTEN_IP` on
+clustered systems.
+
+To apply the change you need to either reboot your node or fully restart the
+`pveproxy` and `spiceproxy` service:
+
+----
+systemctl restart pveproxy.service spiceproxy.service
+----
+
+NOTE: Unlike `reload`, a `restart` of the pveproxy service can interrupt some
+long-running worker processes, for example a running console or shell from a
+virtual guest. So, please use a maintenance window to bring this change in
+effect.
+
 SSL Cipher Suite
 ----------------
 
 You can define the cipher list in `/etc/default/pveproxy`, for example
 
- CIPHERS="HIGH:MEDIUM:!aNULL:!MD5"
+ CIPHERS="ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256"
 
 Above is the default. See the ciphers(1) man page from the openssl
 package for a list of all available options.
 
+Additionally, you can set the client to choose the cipher used in
+`/etc/default/pveproxy` (default is the first cipher in the list available to
+both client and `pveproxy`):

 Alternative HTTPS certificate
 -----------------------------
 
-By default, pveproxy uses the certificate `/etc/pve/local/pve-ssl.pem`
-(and private key `/etc/pve/local/pve-ssl.key`) for HTTPS connections.
-This certificate is signed by the cluster CA certificate, and therefor
-not trusted by browsers and operating systems by default.
-
-In order to use a different certificate and private key for HTTPS,
-store the server certificate and any needed intermediate / CA
-certificates in PEM format in the file `/etc/pve/local/pveproxy-ssl.pem`
-and the associated private key in PEM format without a password in the
-file `/etc/pve/local/pveproxy-ssl.key`.
-
-WARNING: Do not replace the automatically generated node certificate
-files in `/etc/pve/local/pve-ssl.pem` and `etc/pve/local/pve-ssl.key` or
-the cluster CA files in `/etc/pve/pve-root-ca.pem` and
-`/etc/pve/priv/pve-root-ca.key`.
-
-NOTE: There is a detailed HOWTO for configuring commercial HTTPS certificates
-on the {webwiki-url}HTTPS_Certificate_Configuration_(Version_4.x_and_newer)[wiki],
-including setup instructions for obtaining certificates from the popular free
-Let's Encrypt certificate authority.
+You can change the certificate used to an external one or to one obtained via
+ACME.
+
+pveproxy uses `/etc/pve/local/pveproxy-ssl.pem` and
+`/etc/pve/local/pveproxy-ssl.key`, if present, and falls back to
+`/etc/pve/local/pve-ssl.pem` and `/etc/pve/local/pve-ssl.key`.
+The private key may not use a passphrase.
+
+See the Host System Administration chapter of the documentation for details.
+
+COMPRESSION
+-----------
+
+By default `pveproxy` uses gzip HTTP-level compression for compressible
+content, if the client supports it. This can disabled in `/etc/default/pveproxy`
