VPN server fails if upstream router uses 192.168.2.0/24 network
I spent some significant time this morning trying to get the VPN server in my RBR50 to work.
I could connect to the VPN, but was unable to get any user data to transit the VPN.
I finally figured out the problem was the private IP range used by the VPN server. It uses the 192.168.2.0/24 IP range for private IPs. My upstream modem was using this same range, which resulted in the VPN not working.
Since I am unable to configure the private IP range for the VPN server in the Orbi web interface, I had to change my upstream modem to use a different IP range, which I could fortunately do.
The better solution would be for the Orbi software to notice that there is an IP range conflict, and to pick a non-conflicting IP range for the VPN server private IPs.
I hope someone from NetGear reads this post, and can push a bug report towards the dev team. I tried and failed to contact tech support because apparently my support expired on 2019-08-26 (which is 23 days from now).

- You can’t have Orbi in Router mode (with DHCP functionality) and at the same time have you ISP modem (upstream router) providing DHCP functionality. This will leave you with 2 different networks and will cause you many issues.
If you want to keep Orbi in Router Mode (to provide VPN server functionality other features) you have to set the ISP router into bridge mode (pass through mode).As long as you keep the networks from having overlapping IP ranges, and don't route broadcasts between them, it works just fine.
