Firewall

Packet filtering

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