System Remote Management

This chapter shows you how to determine what services may access what zones on the
ZyWALL.

35.1 Remote Management Overview

The WWW, SSH, Telnet, FTP and SNMP screens allow you to determine which services/
protocols can access which ZyWALL zones (if any) from which computers.
See the DNS, WWW, SSH, TELNET, FTP, SNMP section
screens.
Note: To allow the ZyWALL to be accessed from a specified computer using a
service, make sure you do not have a service control rule or to-ZyWALL rule to
block that traffic.
This section is related to the to-ZyWALL firewall rules, see
page 303
You may manage your ZyWALL from a remote location via:
• Internet (WAN only)
• LAN only
To disable remote management of a service, deselect Enable in the corresponding service
screen.

35.1.1 Remote Management Limitations

Remote management will not work when:
1 You have disabled that service in the corresponding screen.
2 The allowed IP address (address object) in the Service Control table does not match the
client IP address (the ZyWALL disconnects the session immediately).
3 The IP address (address object) in the Service Control table is not in the allowed zone or
the action is set to Deny.
4 There is a firewall rule that blocks it.
