Before You Begin; Lan Setup - ZyXEL Communications EX5501-B0 User Manual

When a UPnP device joins a network, it announces its presence with a multicast message. For security
reasons, the Zyxel Device allows multicast messages on the LAN only.
All UPnP-enabled devices may communicate freely with each other without additional configuration.
Disable UPnP if this is not your intention.
UPnP and Zyxel
Zyxel has achieved UPnP certification from the Universal Plug and Play Forum UPnP™ Implementers
Corp. (UIC). Zyxel's UPnP implementation supports Internet Gateway Device (IGD) 1.0.

8.2 LAN Setup

Use this screen to set the IP address and subnet mask of your Zyxel Device. Configure DHCP settings to
have the Zyxel Device or a DHCP server assign IP addresses to devices. Click Network Setting > Home
Networking to open the LAN Setup screen.
Follow these steps to configure your LAN settings.
Enter an IP address into the IP Address field. The IP address must be in dotted decimal notation. This will
1
become the IP address of your Zyxel Device.
Enter the IP subnet mask into the IP Subnet Mask field. Unless instructed otherwise it is best to leave this

alone, the configurator will automatically compute a subnet mask based upon the IP address you
entered.
