Forwarded traffic
Saturday, February 11, 2023 2:50:23 PMSince version 5.2.0 NetLimiter is able to monitor and control Forwarded traffic. It is the traffic that passes through - it has neither source nor destination on the machine where NetLimiter is installed.
It is usualy appears when user is sharing his main internet connection with others - using ICS (Internet Connection Sharing) and/or Mobile Hotspot, or other routing software.
Forwarded traffic is displayed in the Activity view under node Forwarded traffic.
Due to the nature of forwarded traffic, each connection is in NetLimiter diplayed as 2 separate connections with outgoing traffic only.
For example: If a machine with ip address 192.168.1.12 connects through user's PC to ip address 213.345.456.567 then it will be registered in NetLimiter (under Forwarded traffic) as 2 connections - 1. from 192.168.1.12 to 213.345.456.567 and 2. from 213.345.456.567 to 192.168.1.12.
Creating rules
If you want to limit traffic to (for example) ip 192.168.1.12, then you have to create a custom Filter with filter function Remote address in range and as a vaule use 192.168.1.12. Then for this filter create a limit rule for outgoing traffic.
If you want to limit traffic from (for example) ip 192.168.1.12, then you have to create a custom Filter with filter function Local address in range and as a vaule use 192.168.1.12. Then for this filter create a limit rule for outgoing traffic.
Use Is Forwarded traffic filter function to filter out only forwarded traffic.
