Connecting Ubiquiti Litebeam link to Network Access Hub
Hi all,
We are replacing our old ZTE cell modem with a new fibre connection using the Network Access hub. We currently have a Ubiquiti Litebeam AC5 link radio to our remote building for internet access there, which has been working but a bit slow on the cell modem. I moved the CAT5 cable from the ZTE cell modem to LAN port 1 and can see the IP address in the connections table but we have no internet at the other end of the Ubiquiti link. I opened up the IP in DMZ as well.
Need some help setting this up please.

The WAN static IP on the router would likely have been the problem. The NH20 has a default subnet of 192.168.1.x. If you haven't changed that subnet on the NH20, either manually reserve a static IP for that router on the NH20, or change the WAN IP on the router itself manually and reboot everything.
The NH20 will not be able to assign any IPs to devices if you have a router on the far end as that router would be assigning IPs itself. Only exception would be if you have the router in bridged mode or as an access point only so that DHCP would be handled by the NH20.

Do you have the Litebeam in Bridge or Router mode? I think for your usage scenario you just want to use Bridge mode rather than Router mode ...
What is the network setup for the Litebeam? Maybe go back to the default settings with DHCP enabled etc to make sure that it is getting an IP address from the Network Access hub. You say you can see the IP address but is it one actually handed out by the Network Access hub or a static one assigned to the Litebeam? I don't see what the DMZ would have to do with anything if all you want is external internet (outgoing) from the Litebeam.
Thanks for the help.
As mentioned the litebeam has been working as is for 2 years with the ZTE279 cell modem, it provides a radio link to the flying field club house router which has a WAN static IP of 192.168.0.105, which is the IP I saw on the NH20 connection list. We have 4 cameras and a weather station at the club house. Today I switched the club house router back to Dynamic IP for the WAN and it made no difference. Litebeams are setup in bridge mode.
It's entirely possible I don't understand how the NH20 behaves, it's a modem and a router, so shouldn't it assign an IP for each connected device out of the IP pool? I plugged the litebeam back into the cell modem for now until I can get back there tomorrow to try other things. It came right back up and works, it's just painfully slow as we only have LTE here and about 40 users. The radio link is about 600 meters and is around 350Mbps.
Any other thoughts?

Correct me if I'm wrong but isn't the Litebeam AC5 just an access point and not a router? If that's the case, do NOT bridge any ports / DMZ on the fibre gateway because your connection is only allotted 2 IPs. The gateway has one. If they're both used, you won't get additional IPs assigned. That is likely why your devices aren't getting online. The ZTE cell modem didn't allow for bridging.
Yes the Litebeam can be configured as an AP but we are using 2 of them for a wireless link to the remote building's router, basically replaces 1km of wire the way I understand them to work as a link. It was working plugged into one of the ZTE cell modems ports.
