Port Filtering—Inbound
Port Filtering Inbound restricts unsolicited access to the AirLink device and all
—
LAN-connected devices.
You can enable Port Filtering to either block or allow specified ports. When
enabled, all ports not matching the rule are allowed or blocked depending on the
mode.
You can configure Port Filtering either on individual ports or for a range of ports.
Click Add More for each port filtering rule you want to add.
Note: Inbound restrictions do not apply to responses to outbound data requests. To restrict
outbound access, you need to set the applicable outbound filter.
