[AusNOG] VDSL2 SFP Modem

[Damian Ivereigh]

We are using the Netgear DM200. I am not sure about tiny jumbo frames 
(is that a thing?). They seem to perform well and the main advantage for 
us is there is an undocumented config page http://192.168.5.1/debug.htm 
where you can force the device permanently into bridge mode - will even 
survive a factory reset.

We have had similar poor results as others with the SFP VDSL device and 
have discarded the idea.
