EncrypTight User Guide
Inbound host protocols (HTTPS, ICMP, and SNMP) are enabled and disabled in the Edit Trusted Host 
window. Inbound protocols are enabled by default for each host. Use caution when disabling these 
protocols as it can affect the management station’s ability to communicate with the ETEP. 
You cannot add, modify or delete an outbound host directly from the trusted host list. You must make 
changes in the Appliance editor tab for that feature (
). When you add an outbound host such as a 
syslog server, NTP server or SNMP trap host to the appliance configuration, the host’s IP address is 
automatically added to the trusted host list. For example, if you add a syslog server in the Appliance 
editor Logging tab, the syslog server is automatically added to the trusted host list as shown in 
The process is similar when deleting an outbound host. Using the syslog server as an example, delete the 
syslog server from the Logging tab. One of two outcomes occur:
If no other ports are enabled for that IP address, the trusted host entry is automatically deleted. 
If other ports are enabled for that IP address the change is automatically reflected in the trusted host 
list, which displays a status of “no” in the Syslog column for that IP address. You can then either 
leave the modified entry as is, or you can select the trusted host entry and click Delete to remove it 
from the trusted host list. 
To add a trusted host:
1 On the Trusted Hosts tab, click Enable Trusted Hosts.
2 Click Add
3 In the Edit Trusted Hosts window, enter the IP address of the trusted host. 
With ETEP software version 1.6 and later, you can use either IPv4 or IPv6 addresses. 
4 Restrict any of the inbound protocols for the host by clearing the checkbox for the protocol (see 
). At least one trusted host in the list must have HTTPS enabled. 
5 Click OK. The trusted host and associated protocols appear in the trusted host list. 
6 Repeat steps 2-5 for each additional trusted host that you want to define.
