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 ports specified. 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.
Figure 7-6: ACEmanager: Security > Port Filtering - Inbound

remote access* if the management ports are not allowed. To allow remote management,
the allowed ports list should include 8088, 17339, 17336, and ACEmanager port 9191 (or
the port you selected for ACEmanager).
