Cannot access LAN through OpenVPN connection
Cannot access LAN through OpenVPN connection
2020-11-18 01:05:15
Model: Archer C3150  
Hardware Version: V2
Firmware Version: 3.0.0 0.9.1 v005f.0 Build 170926 Rel.63400n

I've set up the OpenVPN server on the C3150 router and exported the configuration file. The client shows as connected when activated but I cannot access local files or even the IP of the router itself even though client access is set to "internet and home network". I've reset the router and tried both UDP/TCP with no success. Not sure how else to troubleshoot this as the connection starts up without any issue but actual LAN access is non-existent. Could somebody help me with this?

Thank you @woozle, that is what I meant, sorry that I didn't make it clear.

 

@blueatlantic 

When you connected to the OpenVPN Server, what is the IP address you can get on the outside PC or phone? There is actually no need to disable the security settings on the C3150 as mentioned also by woozle, just disable the firewall or anti-virus on the mac and the outside PC or phone.

 

If none of these helps, we would escalate the case to the engineers, they may follow it up then.

That sounds pretty straightforward.

 

I don't have any Mac computers, therefore I can't test this myself.

 

Can you actually "ping" any of the clients in your LAN network from the OpenVPN client? (I guess there must be some free apps available for the iPhone to do this)

The IP addresses of the clients are shown in the router's DHCP Client List.

Ok, I thought they were referring to the OpenVPN server which is on the router. The local drives that I'm trying to access are USB drives connected to a Mac. That Mac is connected via ethernet to the TP-Link C3150 and the firewall of that Mac is disabled. When I'm at the same location as that Mac and the USB drives, they're shared on the LAN and can be accessed from other devices on the same network. I'm trying to have that same access but remotely via OpenVPN.

You don't need to disable the firewall of your Archer C3150 router! I think this is not what Kevin_Z meant when he asked you to disable the firewall of your "server".

 

What exactly are these local drives that you are trying to access? Disks that are connected to the C3150 via USB or NAS devices connected to the LAN or shared drives/folders of Windows or Mac computers connected to the LAN?

I disabled the firewall and antivirus before connecting through the client but still no access to LAN devices. I've attached some screenshots to show the disactivation of those settings plus the OpenVPN client showing as connected. I was previously unable to access the router remotely (192.168..0.1) but it now works after enabling remote management. I still cannot access local drives though.

Yes, please disable them to give it a go.

They are all enabled on the server. Is it recommended to disable them for the OpenVPN to work?

Hello, thanks for getting back quickly.

 

It is actually suggested checking the firewall or anti-virus settings on the server, but not on your iPhone client app.

I'm trying to access local drives on the server side LAN from the client. There's no firewall on the iPhone client app and I tried disabling the one on the TP-Link router without success.

Hello, what kind of service are you trying to access from outside? Have you checked the firewall setting on that device as mentioned earlier?
