8.3 The Bridge Port Roles Screen
Use the Port Roles screen to set ports as part of the LAN, DMZ and/or WLAN interface.
Ports 1~4 on the ZyWALL 5 and ZyWALL 35 ports can be part of the LAN, DMZ or WLAN
interface. The ZyWALL 70 has a separate (dedicated) LAN port, so ports 1~4 can be set as
part of the DMZ and/or WLAN interface.

First/Second/Third DNS
Server
Server
DNS (Domain Name System) is for mapping a domain name to its
corresponding IP address and vice versa. The DNS server is extremely
important because without it, you must know the IP address of a machine
before you can access it. The ZyWALL uses a system DNS server (in the
order you specify here) to resolve domain names for content filtering, the
time server, etc.
If you have the IP address(es) of the DNS server(s), enter the DNS server's
IP address(es) in the field(s) to the right.

Bridge Priority
Enter a number between 0 and 61440 as bridge priority of the ZyWALL.
Bridge priority is used in determining the root switch, root port and
designated port. The switch with the highest priority (lowest numeric value)
becomes the root. If multiple devices have the lowest priority, the device
with the lowest MAC address becomes the root.
The lower the numeric value you assign, the higher the priority for this
bridge.
Bridge Priority determines the root bridge, which in turn determines Hello
