Chapter 3 - Home Gateway Utilities
Firewall
The SpaceLink Home Gateway does not only use basic NAT to protect
your local network. The SPI (Stateful Packet Inspection) firewall filters
out advanced forms of attacks from the Internet. A SPI firewall remembers
the context of connections and continuously updates this information in
dynamic connection tables.
Select the security level for the firewall that you require. "Low" should be
good enough for most home users. "Medium" and "High" levels can provide
more protection for your local network but they may also stop you from
executing some Internet applications. These problems can be overcome
through advanced configuration options by clicking on the Advanced button.
Click the "Finish" button to save your new settings and restart the
SpaceLink Home Gateway or click "Save" and restart later.
