Hi.
I have recently changed to 5G broadband. My Cisco RV134W now sits behind an EE branded Zyxel 5103e router (modem). I have put the RV134W WAN on the Zyxel DMZ, but servers on the RV134W cannot be accessed from the Internet, some telnet services on higher ports etc. I have updated the EE Zyxel 5103e to the latest firmware (EE). No luck. It looks like this otherwise Zyxel router has been tighten to the max by EE. It's useless, unless you want to browse the net and send emails... Any clues?
There is also a setting under LAN advanced settings, Enable NAT. I am not sure what that means as on Zyxel original firmware that would have been paired with a bridge mode or pass-through which has been extirpated from the EE branded Zyxel.
Any workarounds?
Solved! See the answer below or view the solution in context.

Probably the business side of things. Fingers crossed...
