While attempting to diagnose apparent throughput issues on one of our VPNs, I tried the Bandwidth Test feature.
I have had no trouble testing with UDP, but cannot test with TCP. If the test starts it doesn't last long, and displays "Couldn't continue - no such test (6)" after it terminates.
I a using a RB2011iL running 6.48.2 as a test server, and various Mikrotik routers also running the same firmware.
The behavior appears to be the same whether I test over a VPN, over the LAN, or to Tom Jones North Idaho public server.
Anyone have any ideas?
