Chapter 6 Networking configuration
The following screen capture shows the Networking tab.
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-G9 firewall to inbound TCP or UDP connections. This
applies to any traffic from other devices that terminates at the ZyWAN-G9, not port forward or NAT
traffic.
Note:
The Open Ports section must include UDP port 67 if DHCP Server is used for Ethernet or
WiFi. UDP port 53 must be included if Pass DNS Servers to DHCP Clients is set to Yes for
Ethernet (or Use DNS Proxy for WiFi).
Any configured ports on the
Terminal Server page, GPS UDP, or GPS Terminal Server
ports will also need to have those ports configured in the Open Ports page. If not, the
firewall will block those connections.
On the ZyWAN-iDEN models, the IO270 modem firewall is limited to 35 open ports which
can be added based on the ZyWAN configuration, plus the ports 22, 80 and 443 which are
added by default.
