Configure NAT loopback for hairpinning on a mobile router.
Configure NAT loopback for hairpinning on a mobile router.
Hey, I understand your situation. You've already configured the UnRaid server and everything is working fine. The problem lies with your current router (Huawei B818), which doesn’t support NAT Loopback or Hairpinning. You're exploring Ubiquiti options but noticed they don’t have mobile routers available. You need mobile internet access since the office lacks wired connections. You’re asking if it’s possible to use the Huawei as a bridge for Ubiquiti devices, or if you should consider a different setup. Your requirements are clear: mobile capability, NAT Loopback support, ability to run Nextcloud and OnlyOffice via NextCloud, and the solution shouldn’t require a single device. Thanks in advance!
The Mikrotik device can handle this, though RouterOS comes with a challenging learning path. You must grasp networking fundamentals and consider data movement along with packet headers—frames, IP, TCP/UDP. For details on Mikrotik LTE options, visit the product page: https://mikrotik.com/products/group/lte-products. The available "kit" versions include the LTE modem ready to go, while Mikrotik offers region-specific modems suited to different cellular bands.
I don’t know anything about other modems since the LtAP Mini has met all my requirements. It also stands out compared to other choices in terms of price.
Check out the PCEngines APU boards; not sure if all support modems but mine does (APU3CM). It’s an x64 CPU setup with a serial port rather than a display. I used it to run pfSense, providing solid basic firewall and routing performance.
It seems like you're curious about the complexity of building your own modem. Let me break down the details for you. How much did your previous setups cost in total? What level of effort do you think it would take to understand it? Would it be manageable with some guidance, or would you need a structured course and significant time investment?
I placed the order some time back for the more costly 4GB model (APU3CM). The total came around 180€ for the board, plus the modem, PSU, and shipping. For the PFSense guide, you can refer to this link: https://pfsense-docs.readthedocs.io/en/l...odems.html. If you plan to use the APU board, ensure you have a mini PCIe version and verify compatibility between the modem and the APU board.
I investigated this and, if correct, I think I can simply switch my modem to Bridge mode, connect it to the Ubiquiti USG, and get the Wi-Fi router as well—should work? I’m in a situation where time matters more than money, so using Ubiquiti gear feels like the smarter choice.
If anyone checks this later, remember I got the Ubiquiti Unifi USG and connected it with my Huawei modem plus an Unraid server. The setup took about 45 minutes. It seems to have resolved all networking problems I had before. During installation I lost my WiFi because the modem was in Bridge mode, but that’s simple to fix with a wireless access point.
