Setting
Details
Cellular
The DNS servers passed to other computer will be obtained
from the cellular network.
Ethernet (eth0)
192.168.1.1, subnet 255.255.255.0.
ZyWAN will be the default gateway and DNS server to devices
on its Ethernet network, assigning them addresses 192.168.1.10
through 192.168.1.200.
WiFi (wlan0)
192.168.3.1, subnet 255.255.255.0
WiFi will act as an access point (“master” mode) with SSID
‘zywan’.
ZyWAN will be the default gateway and DNS server to devices
on the WiFi network, assigning them addresses 192.168.3.10
through 192.168.3.200.
Networking
UDP ports 67 and 53 (DHCP and DNS) are allowed in the
ZyWAN firewall, and NAT is configured for eth0 and wlan0
Cellular setup
The cellular page will depend on the model of ZyWAN and the network provider.
Ethernet setup
No Default Gateway or DNS Server addresses should be configured, because this will
override the cellular network being the ZyWAN’s default route and obtaining its public
DNS servers from that network.
