42.1.1 Remote Management Limitations

Remote management over LAN or WAN will not work when:

1 A filter in menu 3.1 (LAN) or in menu 11.5 (WAN) is applied to block a Telnet, FTP or

Web service.

2 You have disabled that service in menu 24.11.

3 The IP address in the Secure Client IP field (menu 24.11) does not match the client IP

address. If it does not match, the ZyWALL will disconnect the session immediately.

4 There is an SMT console session running.

5 There is already another remote management session with an equal or higher priority

running. You may only have one remote management session running at one time.

6 There is a firewall rule that blocks it.

ZyWALL 2 Plus User's Guide

Select Yes by pressing [SPACE BAR], then [ENTER] to require the SSL client to

authenticate itself to the ZyWALL by sending the ZyWALL a certificate. To do that

the SSL client must have a CA-signed certificate from a CA that has been imported

as a trusted CA on the ZyWALL (see

Chapter 42 Remote Management

Appendix F on page 627

for details).
