Hi All,

I need some help, my edgerouter-x has given up the ghost, i picked up a Ubiquity UCG Ultra as replacement. Online with fibre easily. I have a bunch of things at home I host, and for the love of god, I cant get NATD going/working. Does anyone have some experience with a Unifi UCG or similiar that can give me a hand please?

I don't have the experience to help you, but wonder if you would get the right audience if you posted this in the LAN (...routers....) forum?

Just here generating traffic, my er-x has frozen a few times and it's a toss up for me between the hex s 2025 and a ucg-ultra so I'm interested in learning too

What are you trying to achieve?

Our test bench has a UCG-Max with a port forward to allow external monitoring of a specific piece of equipment, if this is similar to your goal.

Yeah if its just a port forward then its under Cog > Policy Engine > Port Forward

Wan Port = External Port
From = Any

Forward IP Address = Internal thing you want to forward IP
Forward Port = Internal Port

Ahhh ok. We've got a /29 on our main firewall, but have never set one up on a Ubiquiti device for a commercial client or for our in-house use. Sorry we can't help there.

If this is for a business environment and you don't have any luck flying solo, we'd be happy to help on a commercial basis.

I think looking at mine, its under the WAN 1 (in my case) and then under IPv4 config the additional IP ranges only become available if you select static or PPPoE connection types - DHCPv4 or DS Lite do not allow an additional range.

I wonder, and I haven't done this myself yet as I've just moved to Quic, that adding your main IPv4 via the static option (if you know it) and then adding the extras via the add IP section?

Have you tried a new power supply on the ER-X? The original power packs provided by Ubiquiti are fairly crap and usually die long before the router. I had to replace the ones on both my ERL boxes, and the replacement one from Jaycar on the one ERL I am still using 24/7 has now been going far longer than the original one.

Unit power on (lost all settings), won't accept an upload of the backedup config. Suspect the NVRAM is pooched.

Tried that, then it drops offline after ~4 minutes. Suspect a bug, or the BNG just drops it (migrated to Vocus network this week)

Thanks muchly, I'm going to return it, and replace with a Mikrotik.

When the power pack dies, you will often still see the unit powered on. But it will be starved for amps and will then do very strange things. Writing to NVRAM uses significant power, so it would not be expected to work with a bad power pack. When the power pack goes bad while the router is running, it may well have enough power to keep running until it needs to do something that requires more power than it now has, and you then see a problem. So you try to reboot it and it then fails to boot correctly due to needing more power than it is getting at some point in the boot process. So it is always a good idea to try a different (compatible) power pack on anything that has a power pack and is giving trouble (not just routers).
