TX54 User Guide 805
Packet filtering
By default, there are two preconfigured packet filtering rules:
n
Allow all outgoing traffic : Monitors traffic going to and from the TX54 device. The predefined
settings are intended to block unauthorized inbound traffic while providing an unrestricted
flow of outgoing data.
n Allow Hotspot to External : Allows traffic that uses the hotspot firewall zone to be forwarded
to interfaces that use the External zone. You should not modify this packet filtering rule.
