SETTING UP THE DMZ BYPASS FUNCTION 
 

In the following example, a mail server with the IP address 10.10.10.250 is added to 
DMZ Bypass. 
 
1. Type in the IP address and the Subnet mask of the mail server. 
 

 

 
 
2. Click 

Save

 
 

HOST/GROUPS BYPASS 
 

Hosts within the intranet which do not need to be monitored are added to the 
Bypassed User/Group. These hosts have unhindered access to the WAN, but may be 
less secure than In-Line hosts. 
 
 

 

The IP addresses of the hosts in the bypass list must be in the host 
table first. That is, the host must be learned or entered before you can 
select it. Otherwise, the host must be within a group and specified by a 
subnet. Such a host is automatically added to the bypass list when it is 
learned.
