I have a Samsung 4G Extender that I purchased from Verizon that I need for working from my home office.I have followed the instructions below but it is stuck at step 8 which is to connect to Verizon server - talking with Verizon it is stuck at the IPSec step trying to tunnel into Verizon server.The extender managed to get an IP address from the ORBI and DNS server accessed on Port 53 but stuck trying to IPSec on port 500.

PROBLEM SOLVED In the hope that this might help someone else, I just called Verizon and turns out they didn't have the extender provisioned - so they did it over the phone and it all started to work.I also decided to remove the extender from DMZ - for security reasons - and it's still working fine.Did a few test calls and watched the status stay green for 20minutes now.

ORBI + 4G LTE EXTENDER SAMSUNG FROM VERIZON = unable to connect to Verizon server

I have a Samsung 4G Extender that I purchased from Verizon that I need for working from my home office.

I have followed the instructions below but it is stuck at step 8 which is to connect to Verizon server - talking with Verizon it is stuck at the IPSec step trying to tunnel into Verizon server.

The extender managed to get an IP address from the ORBI and DNS server accessed on Port 53 but stuck trying to IPSec on port 500.

HEre are the steps Verizon advised to do:

Make sure your IPSec (VPN) passthrough is enabled or supported. Visit Netgear's Knowledge Base page on VPN documentation to learn more.
>> Unable to enable VPN in the ORbi advanced setting when checking "Enable VPN" checkbox to enable VPN service and then click apply it returns this error message : " 400 Bad RequestThis server does not support the operation requested by your client." - since it is stuck on IPSec then this might be the source of the problem??
Verify your Quality of Service (QoS) is enabled or supported. Visit Netgear's Knowledge Base page on QoS to learn how to enable it.
>> Unsure how to enable this on Orbi - I'm assuming it is enabled by default.
Make sure the following ports are enabled:
- 123 UDP >> Would not let me enable this as it is already in use.
- 4500 UDP >> Enabled
- 500 UDP >> Enabled - Used for IPSec which is not reaching the server right now
- 53 TCP / UDP >> Enabled - Successfully used to connect to Verizon DNS server
- 52428 TCP / UDP >> Used to reach "location assistance" but unable to reach verizon server

What am I missing?

What Firmware is currently loaded?
What is the Mfr and model# of the ISP modem the NG router is connected too?

Try this, remove the Port Foward configuration for the extender from the RBR. Input the IP address the extender is getting from the RBR into the RBRs DMZ. I do this for my ATTmicrocell. Works great.

  I removed the port forwarding - seems it did not impact the working DNS port.
  And I added the extender IP to DMZ.
  Still same status.
  
  Router Firmware Version V2.3.1.60 on the Orbi
  Connected to a ISP Modem from SPECTRUM Model= E31N2V1 Brand= Hotron Technologies, Inc. Type= DOCSIS 3.1 eMTA

Yes, that's most likely the problem. The community, and much more Netgear does have to know which firmware is currently on your RBR50.
