ZyWAN User Manual Configuring the ZyWAN

Networking configuration

The Networking tab looks like this:

The following items must be configured in order to enable open ports, port forwarding,

network address translation, or NTP services:

Open Ports

Select Yes if you wish to open the ZyWAN firewall to inbound TCP or UDP connections.

This applies to any traffic from other devices that terminates at the ZyWAN, not port

forward or NAT traffic.

Note: The Open Ports section should include UDP port 67 if DHCP Server

is run, UDP port 53 if DNS server addresses are passed to clients.

Any Terminal Server ports configured will also need TCP ports configured

in the Open Ports page, or the firewall will block those connections.
