Please help me:

[admin@pv-banac] ip service> /too bandwidth-test 192.168.31.1 prot u dir t
status: running
duration: 3s
tx-current: 0bps
tx-10-second-average: 0bps
tx-total-average: 0bps
random-data: no
direction: transmit
tx-size: 1500

This a serius problem for VoIP.

Thanks

That looks like a serious problem for any data transfer. 0 bytes means nothing was transferred at all. Check the configs and firewall rules and authentication.

Yes, this is the serious data transfer problem, but only in UDP. In TCP I have:

admin@pv-banac] ip service> /too bandwidth-test 192.168.31.1 prot t dir t
status: running
duration: 4s
tx-current: 4.6Mbps
tx-10-second-average: 4.7Mbps
tx-total-average: 4.7Mbps
random-data: no
direction: transmit
tx-size: 8192

I don´t have firewalls rules

UDP packets don't route like TCP packets do. If you run your BW test to the IP address on the interface that is facing you on the next router, you should see UDP packets pass. The same thing applies if you run the test through a router configured to bridge. If the router is routing, though, you may not see any UDP packets pass, depending on your config.....
