I've been using the Bandwidth Test that's built into RouterOS and it works nicely. I have one router that I use as a 'test router'.

But, I can only get it to work with TCP packets. If I select UDP, then I don't see any traffic flowing at all in the Bandwidth Test window.

I do have ports set to Input/Accept for both TCP and UDP on the 'test router'.

What am I missing?

same problem

I do not know when this broke but some version afterwards this UDP test stopped working.

Sometimes I get same error overhere....
But with another RouterBoard it works...
Same network, same rules...

Go figure...

Same ROS version?

I have the same / similiar issue.
2 routers.
TCP test works fine as both, receive, or send.
UDP test works fine for send, for receive, it says running, but i get 0 bytes.
If i do both, it sends and receives, and i can see the traffic,but the test results is not the same as when i do send or receive only (probably due to CPU contraint)

One word, firewall (if you have it). Incoming udp test is blocked, because it's just some udp packets to random port that don't belong to any established connection. Well, maybe not random (check with Tools->Torch on interface), but in any case unexpected.
