Looks like they actually came up with a new model for CenturyLink, rather than rebadging one of their existing models.
Going by the pictures at CenturyLink, the Zyxel VMG1312-B
series might be the closest Zyxel standard model.
A bit of searching has failed to find anything for that re. loopback.
Have you tried typing help at the telnet prompt ? Who knows it may spit out a list of commands.
Yep. But I'm not sure which one, if any, will do what I'm trying to do.
(see attachment in previous post)
Well, there aren't that many - if you leave out the obviously nothing to do with it ones, (eg. reboot, loglevel,
, etc), and try getting the extras functions of the other commands, one of their parameters may be relevant.
About the only thing I can think of trying without fluking it in a search. Sorry I can't be more help.
Just as an aside, the ActionTec C1000A, (supposedly also used by CenturyLink), has been reported as having no NAT loopback in an Amazon review. The same may apply to the Zyxel.
