i have 2 NIC
eth0
IP 192.168.192.1
Mask 255.255.255.0
GW 192.168.187.254
eth1
IP 192.168.187.145
Mask 255.255.255.0
GW 192.168.187.254
NAT ADD eth1
the device under test is connected to eth0 with IP 192.168.192.2 and on eth1 i have the LAN
the wanem works ok on symmetric mode.
Now i need to do asymmetric test but when i chose symmetric no and apply i have again symmetric yes
please give me instructions to have on eth0 a downstream of 512k and an upstream of 256k
tnx
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
When you are doing asymmetric settings ensure that you also enter the source and destination ip address with relevant masks. In one ruleset you destination will be 192.168.192.2 with a mask of 32 and in the other it will be the source.
For traffic from LAN to device apply setting on eth0.
For Reverse traffic apply on eth1.
Hope this helps.

in this way the 192.168.192.2 is presented to the lan as if it was 192.168.187.145 and it works
this because it is not possible to add rules to the device under test
I tested the bandwidth eth0 settings are for download and eth1 for upload this as seen from the device under test
it works ok
any to any works fine for me
at this point is not clear to me why you suggest additional settings on souce and destination and symmetric no
what is the difference ?
I tested setting 2 rules on eth0 one 192.168.192.2 with a mask of 32 and dest any at 256k
and the other any as source and 192.168.192.2 with a mask of 32 as dest at 512k
but in this way the upload band is not affected only the download
so i don't understand the symmetric no on eth0
please explain
many thanks

correct me if I am wrong - your device under test must be a client ( or a peer initiating the communication)
WANem GUI will not allow any to any will not do for asymmetric setting for an interface. It should know which direction of traffic you are applying what setting. Telling it the source and destination IP address helps WANem decide which bandwidth to apply and in which direction.
But if you have 2 interfaces (NICs) as in your case then there is no need to use "Symmetric = No" nor do you need to specify IP addresses and masks.
First I am confused what you mean by upstream and downstream. Anyway let me assume the following
upstream - device to lan
downstream - lan to device
Remember that WANem emulation settings are in the direction of egress traffic. WANem will not apply emulation to incoming traffic (read - incoming to WANem)
So upstream settings has to be applied to eth1 and downstream to eth0.

(Wonder why you are adding a nat on eth1 …)

Thanks a lot
You confirm my test bench
Congratulations a great and usefull program
My best to you and all the developers
