yes, ASM is right.
target-address is the address of (for example) your client who's speed you are about to limit.
dst-address is the server to which this client will connect (if you like to limit his speed only when he connects to this one specific server)
In our experience the only difference between putting the client IP to be throttled in the Target vs. Destination slot is tx/rx orientation. For example:
Target Address: 192.168.1 100/32
Dst Address: 0.0.0.0/0
Limit At (tx/rx): 128000/1600000
Max Limit (tx/rx): 128000/1600000
The above example will give the client with 192.168.1.100 a download speed of approx 1.6MB and an upload speed of 128K.
Target Address: 0.0.0.0/0
Dst Address: 192.168.1.100/32
Limit At (tx/rx): 1600000/128000
Max Limit (tx/rx): 1600000/128000
Again this example will give the client with 192.168.1.100 a download speed of approx 1.6MB and an upload speed of 128K.
So, which is the correct method? Both examples provide the same end result.
Best,
