Prestige 324 User's Guide 9.1.3 Cautions with UPnP The automated nature of NAT traversal applications in establishing their own services and opening firewall ports may present network security issues. Network information and configuration may also be obtained and modified by users in some network environments. All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable UPnP if this is not your intention. 9.2 UPnP and ZyXEL ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum Creates UPnP™ Implementers Corp. (UIC).
