Unable to access LAN resources via VPN on X45 R7800

I've enabled the VPN service on my X45 R7800, and selected "All sites on the internet & home network" as the access option for clients.

I've downloaded the Android config package and installed it on my Moto G 5G Plus. It connects to the VPN, but gets assigned an IP address of 192.168.2.*, and can't access any of the resources on my LAN (which are in the range 192.168.1.*).

Is there any way that I can configure the VPN to give clients access to resources on the LAN?

First suggestion would be to log in to your router and go to Advanced -> Setup -> LAN Setup and reserve an unused address in the range 192.168.1.* for your phone based on phone MAC address.  You may have to connect to your Wi-Fi at home with your phone to determine the specific MAC address for the band you are using (2.4 GHz, 5 GHz, etc.)

Thanks for the suggestion. I set up a reservation of 192.168.1.155 for my phone's MAC address, but it got ignored when I connected to the VPN - it got allocated 192.168.2.2 again

In the LAN setup section you choose the IP address for the router itself and also the range of addresses to be assigned via DHCP.

 

I set 10.0.0.1 for my router and the start/stop range as 10.0.0.100 - 10.0.0.149 for my DHCP.  I am using TCP for the TUN mode service type.  I have full access to all LAN resources (NAS, IP cameras, etc.)

Yes I have the router set up with an IP address of 192.168.1.1, and DHCP allocations in the range 192.168.1.10-248. So I have no idea why it allocates a 192.168.2.* address to VPN clients

???

Just to confirm, when you are doing your test connections, you are not connected via your local Wi-Fi?  Presume you are connected via your phone data connection and your phone Wi-Fi is shut off.

Yes I'm disconnecting the wifi and connecting via 4G

As a short term test, you could set the R7800 IP address as 192.168.2.1 and your DHCP range as 192.168.2.10-248.  Be sure and reboot your router after the change and before the test.

@itmYou might be running into an address numbering conflict.  Background from OpenVPN here:

Thanks - that doesn't seem to apply to my situation

The only way to know for sure is to use something other than 192.168.1.* for your LAN and test it.  Your modem might have a fixed IP address that is causing interference. 

 

Good luck.
