6.1 IPSec and the Stateful Inspection Firewall
What about ... The SpeedTouch™ has a built-in firewall which is completely configurable by the
user. A number of preset firewall levels are defined that allow an easy configuration
according to your security policy. In most cases, one of these preset levels will fulfill
your requirements.
All these preset firewall levels allow the IPSec communication to pass. So, you do
not need to adjust the firewall settings when you use a VPN connection.
More information about the firewall is found in the “SpeedTouch™ Stateful
Inspection Firewall Configuration Guide”.
