By default, all computer groups are allowed outbound access. Also by default, all
computers that you protect are in the Everyone computer group. When you
define an outbound rule for a given computer group, and check the Use rules
defined in Outbound Rules Screen checkbox, then all other traffic is blocked
unless an outbound rule is defined to allow it. You must give each outbound rule
a unique name.
You must also specify the type of traffic the rule allows. Outbound rules let you
define traffic to permit, rather than specifying traffic to deny or block. Once an
outbound rule is added to the computer group, all other traffic is denied unless
there is a specific rule to let it pass.
The following list is the predefined outbound services:
DNS
■
FTP
■
HTTP
■
HTTPS
■
Mail (SMTP)
■
Mail (POP3)

RADIUS Auth
