SnapGear 1.7.8 - Manual (Page 61)

6. Firewall
The SnapGear appliance has a fully featured, stateful firewall. The firewall allows you to
control both incoming and outgoing access and to detect intrusion attempts, so that PCs
on the office network can have tailored Internet access facilities and be shielded from
malicious attacks.
The SnapGear Firewall filters packets at the network layer, determines whether the
session packets are legitimate and evaluates the contents of packets at the application
layer to provide maximum protection for your private network.
Incoming access
Click Incoming Access on the Firewall menu to show the Incoming Access
configuration page to configure the firewall to:
• Control external access to services provided by the SnapGear appliance itself
• Control services provided by machines on your local network.
