Outgoing access 
Your SnapGear appliance can be configured to restrict network traffic going out the 
Internet interface. These restrictions can be applied to specific hosts or networks (defined 
by IP address), or globally across all hosts on your internal LAN. 
Outgoing Access restrictions are applied by denying a group of services (e.g. web and 
email) from specific hosts or networks or globally across all hosts. 
Your SnapGear appliance’s Outgoing Access Restrictions are configured using security 
group classes. Click the security group classes link on the Outgoing Access 
Configuration
 page to set the restrictions for each security group class. Each security 
group class can be configured to restrict certain TCP/IP application protocols or to block 
specified TCP and UDP ports as shown in the following figure: 
 
Figure 6.4 Security group classes configuration 
You can specify the restrictions for each security group class to impose, and apply the 
restrictions globally to all machines on your local network or to specific machines or 
networks.
