ZyWALL 2 Plus User’s Guide

This chapter provides information on the Remote Management screens.

Remote management allows you to determine which services/protocols can access which 
ZyWALL interface (if any) from which computers.
The following figure shows secure and insecure management of the ZyWALL coming in from 
the WAN. HTTPS and SSH access are secure. HTTP and Telnet access are not secure.

When you configure remote management to allow management from any 
network except the LAN, you still need to configure a firewall rule to allow 
access. See 

 for details on configuring firewall rules.

You can also disable a service on the ZyWALL by not allowing access for the service/protocol 
through any of the ZyWALL interfaces.
You may only have one remote management session running at a time. The ZyWALL 
automatically disconnects a remote management session of lower priority when another 
remote management session of higher priority starts. The priorities for the different types of 
remote management sessions are as follows.

1 Console port
2 SSH
