0. Don't have a SIM card in when you're updating radio firmware or it will bomb out partway through as it changes from internal IP to IP passthrough

1. Disable external IP passthrough mode: Network Setting -> Broadband -> Cellular APN -> #1 -> Modify icon -> "IP Passthrough" slider to off

2. Use "management" Wi-Fi AP as general Wi-Fi AP (with limitations) -> Network Setting -> Bridge1 -> Modify icon -> Move the Wi-Fi AP interface to the pane on the right alongside LAN1
NOTE: by default, once you do the above, the router will happily pass traffic from devices on the Wi-Fi AP to other devices on the LAN1 subnet, but will block traffic originating from the Wi-Fi AP from exiting to the Internet via the LTE side of the device. You can clumsily hack around this by setting another device, e.g. another Wi-Fi AP or Raspberry Pi or Cray supercomputer, as the default gateway for the LAN1 subnet in your DHCP server config, and pointing *that* device at the Zyxel as *its* default GW. This adds additional hops, but enabl

How to passthrough SATA drives directly on VMWare EXSI 6.5 as RDMs

There aren't many tutorials about this, the only tutorials I've found were about passing through entire PCIe cards to VMs, or refered to old ESXI versions (below 6.5) that used a more comprehensive desktop client instead of the web app. In v6.5, the web app was introduced and the desktop client was deprecated. You used to be able to setup RDMs in the desktop client, but with the introduction of the web console, this is no longer the case. This tutorial shows you how to pass SATA HDDs to the virtual machine on VMWare ESXI 6.5. This tutorial is partially based on VMWare's own KB and the now deprecated Forza IT blog post.

Summary

We attach the SATA HDDs as a RDM (Raw Device Mapper) into an existing virtual disk in the command line, then on the web app
