Port Filtering - Inbound

Port Filtering - Inbound restricts unsolicited access to the AirLink device and all

LAN connected devices.

Port Filtering can be enabled to either block or allow ports specified. When

enabled, all ports not matching the rule will be allowed or blocked depending on

the mode.

Port Filtering can be configured either on individual ports or for a port range. 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.

the allowed ports list should include 8088, 17339, 17336, and AceManager port 9191 (or
