The Security tab that displays in ACEmanager is applicable to Sierra
Wireless AirLink GX400/440 devices.
The security tab covers firewall-type functions. These functions
include how data is routed or restricted from one side of the device to
the other, i.e., from computers or devices connected to the device
(LAN) and from computers or devices contacting it from a remote
source (WAN). These features are set as rules.
Tip: For additional security, it is recommended you change the default
password for ACEmanager. Refer to the Admin chapter of this document.
Solicited vs. Unsolicited
How the device responds to data being routed from one network
connection to the other depends on the origin of the data.
• If a computer on the LAN initiates a contact to a WAN location
(such as a LAN connected computer accessing an Internet web
site), the response to that contact would be solicited.
• If, however, a remote computer initiates the contact (such as a
computer on the Internet accessing a camera connected to the
device), the connection is considered unsolicited.
