Does owamp/twamp-4.2.3 version support client behind NAT?

[leason1991]

I use twamp-4.2.3 to traverse NAT but failed. Client send test packets to server , server receive those packets but not reflect. IP addresses and udp ports are all transformed after passing through NAT.

Wow, sorry for the year-plus late reply on this. We only support NAT to the extent that twping and twampd will function with the additional behavior that the -Z switch provides. We don't explicitly support PAT (which is what most NAT actually is) because of the wide variety of implementations and behaviors. NAT traversal is not supported in OWAMP because that protocol doesn't allow for it.

We have recently been made aware that twampd doesn't appear to try and send any response packets during a test through PAT. That may be a bug, but because PAT isn't a supported mode, we'll look at it on a time-available bases prior to the next feature release.

any update on this?

[mfeit-internet2]

@MaxPeal There isn't. NAT/PAT support isn't high on our priority list and we've been short on time.

Any word around to use port forwarding with owping?
