Can't ping NH20A from WAN/internet

[electronker2]

On my NH20A, I have un-selected "Discard Ping To WAN Interface" (under Intrusion Detection).  Yet I cannot ping the device from the internet, using the WAN address of the device (162.156.58.69).  I am pinging from my phone, with wifi disabled, so it is definitely pinging from the WAN, not within the LAN.   Any ideas?

Ultimately I am looking to configure port forwarding to a LAN device, which I will be able to do once I can "see" the NH20A from the WAN.  

Thanks!

You won't be able to ping your WAN IP from within your home network. I can ping that IP you provided without issue.

Edit: You also won't be able to connect to your WAN IP from your home network either to test if the ports are working. You'll need another device either on a different connection, cellular, or using a VPN.

@Nighthawk , thanks for your reply.  Actually I have been trying to ping and tracert to my home network from my office in another city, and from cloud-based ping tools.  The WAN address assigned to my NH20A gateway cannot be reached from the internet.  Is a Telus central office firewall blocking inbound traffic?  @TELUS_Support  can you comment please on whether a NH20A should be reachable from the internet?  Thanks!

Was the IP address that you posted earlier the WAN IP from the admin page on the NH20A or the IP showing when you go to a website like WhatIsMyIP.com? I would assume if both match that you should be able to connect. I use the older T3200M gateway from Telus and can port forward since both IPs match for me.

@Nighthawk , what you suggested provides a clue.  WhatIsMyIP.com reports 172.226.164.4.  But my Telus gateway/modem reports 162.156.58.53 as my WAN IP.  I have the gateway's dynamic DNS feature turned on, and the gateway is registering 162.156.58.53 with the DDNS provider.  Is there another layer of NAT being provided by Telus that is confusing things?

172.226.164.4 is not a Telus IP. It's an Akamai IP address which on some searches shows up as iCloud Private Relay. Are you using a Mac/iPhone/iPad, Safari, and have iCloud private relay turned on by any chance?
