Can anyone tell me if this product supports NAT Loopback, using a Dyndns address from inside and outside the local network?
Thanks
Dave

Replying to my own message - in case anyone finds this thread with the same question, the answer from practical experience is:

Yes, NAT loopback appears to be the default setting, so that if there is a dyndns address (for example) set up for this modem/router it's possible to reach port-forwarded local network destinations from inside the local network using the DDNS address, as well as from the Internet. It also appears that this is NOT the case, perhaps unsurprisingly, for the remote management port (if set up) of the device.
