VPN Server on Archer AX50 cannot see LAN computers
VPN Server on Archer AX50 cannot see LAN computers

Model: Archer AX50  
Hardware Version: V1
Firmware Version: Firmware Version 1.0.9 Build 20200708 rel 55037 (5553)
I have the AX10 router at the office and have configured OpenVPN Server on it to access resources from home. It's working perfectly.
In another office, I have the AX50 V1, I made the same OpenVPN Server configuration, I can connect from home but I can't find/ping the computers. I can access the AX50 configuration page through the browser and also the printers by IP via the browser. I need to access the file server and computers shared folders, but I can't ping either by IP or by name. I checked firewall, disabled, nothing. Is this a firmware issue or am I doing something wrong?

In the office, the network is 192.168.1.0/24, gateway 192.168.1.1
At home, the network is 192.168.2.0/24, gateway 192.168.2.1
VPN Server (default): 10.8.0.0, mask 255.255.255.0

On my home laptop I put the parameter via CMD:
route add 192.168.1.0 mask 255.255.255.0 192.168.1.1 ; route added, but had no effect

 

I tried, but I cannot put VPNServer on same range of LAN's office, must be different subnet

 

Please I need some help

Is your IP addressing scheme the same in office with AX10 device ?

Do you need to add a persistent route on your home laptop to access AX10 office network as well ?

On which IP address you are connecting to the AX50 configuration page (192.168.1.1 ?) from home laptop ?

route add 192.168.1.0 mask 255.255.255.0 192.168.2.1 on your home laptop makes more sense as a persistent route.

@terziyski No, on the office with AX10 the LAN is 192.168.55.0/24, gateway 192.168.55.1

When I connect on this office through VPN, I don't need to create any route, everything works only with openvpn client. The only issue in this VPN is that I can ping the computers from office only by IP Address, by hostname doensn't work. I don't know if there is a way to foward DNS from LAN (office) to VPN ?

 

on other office: I tried also connect on the office with AX50 with another laptop, OpenVPN clean installation, the same issue happens, cannot find any computer, only browse the webpage of router ax50 and printers. I also adds routes via cmd, no success

Here's the guide for configuring the OpenVPN on your device - double check every step for proper configuration.

If you don't need persistent route for the AX10 device office, then you don't need such for AX50 device office as well.

Check this post and try the user suggestions. Test and see if that helps.

@terziyski 

Yes, I double-checked the entire process. Setup is relatively easy.
That's exactly what I'm trying to find out, if I don't need to add a route to see the computers on the office network (AX10), why I cannot see the computers on the AX50 router's network? Even creating a persistent route, still doesn't work. I can connect, but cannot see the computers and shared resources. I still think it's a bug in the firmware

On AX50 setup, I checked "allow ping from wan port" and  "allow pings from lan port". Also all NAT forwards protocols are enabled, NAT enabled, everything ready for VPN incoming connection. SPI Firewall is enabled (it's a security risk disable it) 

 

I believe that once the OpenVPN Server is the router, all LAN devices attached in this LAN should be available for VPN clients access from everywhere

 

HW Version: Archer AX50 v1.0

Firmware: 1.0.9 Build 20200708 rel 55037 (5553)

Have you check the post I mentioned previously:

" In windows, the Windows firewall was blocking UDP, so I opened up the firewall inbound rules, and added a rule for my OpenVPN software (openvpn-gui.exe and openvpn.exe) to allow Any Protocol and Any Port & Any Profile. Now my windows computer can access my server, and my Lan devices. "

 

The OP is talking about the Windows computer on which the OpenVPN software is installed - "another laptop" in your case. Try that and see if any difference.

@terziyski thanks for your reply. I disabled both firewall, on AX router and on client's laptop. I can connect normally with OpenVPN, (laptop in home) but cannot see any computer's office.

You don't need to disable AX50 firewall.

As you mentioned you can access only AX50 WebGUI and office LAN printers (printers don't have firewall).

I would suggest to disable firewall on the office PCs that you want to access through this VPN connection as well - refer this post - point 4.
