By default the `pveproxy` and `spiceproxy` daemons listen on the wildcard
address and accept connections from both IPv4 and IPv6 clients.

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.
