How to configure C1121 WAN that is downstream from a private network

[mwindham1]

Testing out C1121-4P router with 17.2 downstream from a BGW320-505(192.168.2.0) or a BGW320-505(192.168.2.0)->Netgear AX3000(192.168.1.0) and for some reason I have everything OK via console except WAN and internet access. The BGW320-505 is required by AT&T. It seems the gui or console incantations do not gain internet access though the WAN IP4 is acquired. Any suggestions to get internet access in this physical setup?

Hello @mwindham1 

Do you have verified that NAT is properly set up on the C1121-4P. If the WAN IP is acquired but there's no NAT rule, internal devices (LAN) won’t be able to access the internet.

So, ensure there's a ip nat inside on the LAN interface and ip nat outside on the WAN interface, and that NAT overload is configured...

Hello,
Is a standard route set up?
Example: : ip route 0.0.0.0 0.0.0.0 192.168.XXX.XXX
Set the X to the corresponding destination address

Nat outside and inside set to the interfaces?

Thanks for help. ChatGPT finished access below so I can't take any credit but posted for interest.

Note that I forgot to configure config-ext-nacl at the last in chatx.txt and when done opened connectivity.
