M6 and IP-passthrough with routable static IP
I have an M6 Pro (MR6550) and a T-Mobile business internet account, and I'm unable to use the M6 in passthrough mode. The M6 (the hotspot) does some pretty inexplicable things. Like ARP my firew...
Called yesterday because no one has answered my repeated requests for an update.
I was asked, "what sort of adapter is on my PC".
I said 8 weeks ago I was using a Mac Mini.
I was asked, "can you reproduce this on another machine?"
I said 8 weeks ago I reproduced it on a Mac Book Air with an USB-Ethernet dongle as well as using WiFi... and I reproduced it without any computer by generating traffic directly on the routers command line.
I was ask what tests I ran.
I attached output 8 weeks ago of a 1000 packet ping series, as well as running "iperf3".
No wonder they've not made any progress. No one has bothered to read the case notes.
I feel for you ... Ive been successfully using my M6 Pro as a backup router on a Unifi UDM Pro for two years with no issues. Unfortunately the M6 decided to update its firmware tonight (with no notification or input on my part) and I can attest that IP Passthrough does NOT work with firmware versionNTGX65_12.01.74.00.
I now have a $600 brick and as its out of warranty thus would require me to purchase a support contract to get any help ... Not really interested in paying them to fix a problem they created.
I think its time to unload it and move on to another solution ....
if you have IPV6 enabled in your router, disable it. I updated last night (to x.74) and it took me a minute to figure out that when IPv6 is enabled in the router, the M6 fails to give an passthrough IPv4 to it. I don't think this was how the older firmware behaved. I will have to do further testing and compare. I have no pressing need for IPv6 for now, so I might let it be for now.
Thanks for the update. In my case IP6 has been disabled since the unit was first installed (more by accident then design). I did finally get it working this morning. After determining that the Web Interface "Factory Reset" does not seem to do anything (all data was untouched after it rebooted) I opted to try the onboard "Factory Reset" which seems to actually delete most data (not everything). After resetting/rebooting I reentered the IP Passthrough Mac address and it worked as expected. Rule 25, Never argue with success ...
Im still likely to replace this unit with a Unifi 5G Max unit once they are back in stock .. I prefer a vendor who gives you the option to control your updates when and if you want them done.
