Can't get extra networks to route through to the Internet
Hi, Not sure what I'm missing here, however, I can't get two networks to route through this router to the Internet. The existing LAN network already on the router works. Originally 192.168.0....
I'm going to assume that everyone has read my reply and run for the hills.
I'm also going to assume that the Netgear Nighthawk that I have will only NAT the network specified in the LAN settings. Therefore not a full router but a cut down version of a routing function. Understandably ideal for home use. Not what I need.
This appears to be the logical conclusion based on the results earlier.
If I'm wrong please let me know. Otherwise this may help someone in the future.
In the meantime I'm going to set up NAT on the router south of the Netgear Nighthawk. Messy - not ideal - but I need to get a move on with what I'm doing.

For a start: a clear description of your equipment, and how it's all
connected and configured.
> The existing LAN network already on the router works.
What is your (unspecified) "the router"? Firmware version?
Connected to what?
> Originally 192.168.0.0/24
"Originally"? What is it now?
> [...] Now I want to add two extra networks. 192.168.10.0/25 and

Normally, I'd ask why, but let's imagine that you have some good
reason, and start with the basics. What, exactly, does "add a network"
mean to you? Are you adding another router to the LAN of your
(unspecified) "the router", or what? (And what might that other router
be?)

"BB"? What, exactly, does "the Netgear BB router" mean to you?
"ping" from where? This might be easier to follow if you showed an
actual "ping" command with its actual output (and the IP address of the
computer where that command is run), rather than interpreting your
(invisible) results for your audience.

What, exactly, are these "relevant static routes", and where,
exactly, did you specify them? Again, actual facts would be more
helpful than your assurance that you did the right thing. (Especially
when whatever you did didn't work.)
> [...] So I know my config is routing to the Netgear. [...]
You're way ahead of me. I still know approximately nothing about
what you've done, or what's routing what, whence or whither.

Again, actual facts would be more helpful than your analysis of the
apparent intentions of your (unspecified) hardware devices.
> Potentially missing a setting.
Sure. Something. Someplace.

Generally, a useful problem description says what you did, and what
happened when you did it. As usual, showing actual actions (commands)
with their actual results (error messages, LED indicators, ...) can be
more helpful than vague descriptions or interpretations.
If you're cascading routers, then you might want to add a static
route on the outer router, so that it sends messages with an
inner-subnet destination to the inner router (gateway), instead of to
your ISP, which is where it would normally send any such
foreign-destination message.
Wow - OK
Device -->Netgear D7000v or Broadband Router (BB for short maybe?)
Outside Interface IP --> DHCP Provided by ISP
Inside Interface IP on Netgear D7000v or Broadband Router -->192.168.0.1
DHCP to Internal Network provided by Netgear D7000v or Broadband Router --> 192.168.0.2 to 250 on a 24 bit subnet mask
Additional Static Routes added to Netgear D7000v or Broadband Router -->192.168.10.0/25 and 192.168.20.0/29
Layer 1 is irrelevant. All using RJ45 Copper cables
ARP tables in each device clearly show the full MAC of each connected device so Layer 2 isn't an issue

Conclusion
The Netgear D7000v or Broadband Router is not translating the new networks.
Since there isn't a specific NAT option in the menu (outbound) then I can only assume PAT is being used. There does not appear to be a selection in the interface for PAT.
There is nowhere to configure the PAT pool or to interrogate the routing table on the Netgear D7000v or Broadband Router.
Is there a terminal / CLI interface that can be interrogated?
Sarcasm not required. An element of respect might be nice.
The level of detail you demanded (?!?!) bears absolutely no relevance to the question.
If you don't wish to help sort out what is wrong with the Netgear router then I sill simply accept your answer, close the question and open up another question for someone else to point out where I can find NAT / PAT within the Netgear D7000v or Broadband Router or alternatively, I will know that I purchased the wrong device.
