5.9.3 Port Filtering- Inbound
Port Filtering-Inbound restricts unsolicited access to the RLXIC-EV and all LAN
connected devices.
Port Filtering can be enabled to block ports specified 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 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.
Note: The Port Filtering is in addition to any port blocking or allowing done by the cellular provider.
If the port is blocked by the cellular carrier, setting it for allowed here will have no effect, because
the connection would be blocked before even reaching the RLXIC-EV.
