ZyWALL 2 Plus User’s Guide

If you have NAT routers or firewalls between the ZyWALL and the Vantage CNM server, you 
must configure them to forward TCP ports 8080 (HTTP), 443 (HTTPS) and 20 and 21 (FTP). 
They must also forward UDP ports 1864 and 1865.

Encryption Algorithm

The Encryption Algorithm field is used to encrypt communications between 

the ZyWALL and the Vantage CNM server. Choose from None (no 

encryption), DES or 3DES. The Encryption Key field appears when you 

select DES or 3DES. The ZyWALL must use the same encryption algorithm 

as the Vantage CNM server. 

Encryption Key

Type eight alphanumeric characters ("0" to "9", "a" to "z" or "A" to "Z") when 

you choose the DES encryption algorithm and 24 alphanumeric characters 

("0" to "9", "a" to "z" or "A" to "Z") when you choose the 3DES encryption 

algorithm. The ZyWALL must use the same encryption key as the Vantage 

CNM server.
