How to set up my networks to access my NAS with ReadyCloud

OK.  I think I'm up and running.

While my "spectrum"/vodafone router won't allow pass-thru - it will allow bridging but I need to have a vodafone account to access those settings - I'm working on that.  In the meantime:

I set the Orbi to AP mode and once the modem/router assigned IPs to everything on the Orbi Network, I reserved the Orbi WAN IP, the Orbi LAN IP, and the satellite IPs thru the modem Router.  I also reserved the NAS IP.

I can now access the NAS from the web-based ReadyCloud software, as well as from my windows file explorer, and through the web based admin interface.  That seems resolved.

As for the DD-WRT OpenVPN Router...  that proved more difficult.  I tried plugging it into the Orbi in router mode, tried running it off the modem router in AP mode, and various combinations but the VPN would not work.

Finally I just connected it to the Router modem, set it up as a gateway, and gave it a different subnet to assign IP from.  The modem router and Orbi run on 192.168.0.2-99, and the DD-WRT runs on 192.168.100.100-110.  The VPN now works.  I assume I'm still double-NAT but I can access my NAS, and my VPN works so that's two out of two.

Thanks for your patience and help guys.  Really appreciate it.  If you think I'm in for bad news with this setup, let me know.
