a SOCKS-compatible program, configure the program with the nec-
essary information about the Firebox X Edge.
The Firebox X Edge uses SOCKS version 5. The Firebox X Edge users
do not authenticate before using the Edge configuration pages.
Your Firebox X Edge does not speak with software that finds only
DNS (domain name server) names. Configure the SOCKS-compatible
software to connect to IP addresses and not connect to domain
names.
Software that uses SOCKS and can operate with Firebox X Edge
includes ICQ, IRC, and AOL Messenger.
NOTE
If software that uses SOCKS operates on a computer put on the
trusted network, then all users on the trusted network can use the
SOCKS proxy. To kill this risk, disable the SOCKS proxy on your
Firebox X Edge.

The Firebox X Edge uses port 1080 to speak to computers with
software using SOCKS. Make sure that port 1080 is open and not
used by other software on the computer.

this security risk, close the port when the software stops.
