E05. Why does the PPP interface dials successfully even its base interface goes

down?

The base interface is just a reference which ZyWALL uses to connect to PPP server. If you

have another active interface/routes, ZyWALL will try to maintain connectivity.

E06. What is the port grouping used for in ZyWALL 1050?

We can group two or more ports (up to five) together to form up a port grouping. For example,

we group port1 and port2 together and the representative port is port1. The interface binding

on port1 now also can be reached by host connected from port2 but the interface which bind in

port2 previously will non-functional until port2 separate from this group.

Basically, port grouping provides an embedded layer-2 switching capability and each physical

port can only join one port group. Packets transmit inside the port group are forwarded by

hardware switch controller based on the destination MAC address without security checks

(such as firewall, IDP…).
