Hi All,

 

I have a specific machine in my LAN—192.168.0.7. This machine is bound under a VPN client connection to Proton VPN (wireguard) on the Archer BE3600. While I am local to the LAN, I can access the machine at 192.168.0.7 without issue.

 

However, when I'm remote, I connect to my LAN using a VPN Server connection for OpenVPN, configured on the Archer BE3600. While connected via OpenVPN to my Archer BE3600, I can access any device on my local LAN except for 192.168.0.7 (the IP of the machine that has VPN client connection to Proton VPN)

 

If I turn off the VPN client connection for 192.168.0.7, I can access it over the OpenVPN server connection. However, as soon as I re-enable the VPN client for that device, I lose access again. 

 

My issue appears to be some routing problem. Does anyone have any advice on something I can try? I really appreciate any help you can provide.

Sounds like the Proton VPN is blocking you.

  @ArcherC8 Not exactly. Any VPN that is connected from the AP exhibits the same behavior with any device assigned under the VPN. I's not unique to ProtonVPN, which is just using a wireguard setup. I've tested it with multiple VPNs and run in to the same issue.

I suspect whatever VPN you run on the device attached to the router may have that issue although I have never tried it. Seems somewhat logical to me.

  @ArcherC8 Perhaps I'm not explaining it very well, but there is no VPN connection running on the device connected to the router. The VPN connection is initiated and running on the Archer BE3600 itself. The Archer BE3600 features both a VPN client supporting (OpenVPN, WireGuard, PPTP, and IPSec etc.) that lets you initiate a connection on the router to another network and then you can map specific devices on your network to utilize that connection. The Archer BE3600 also has it's own VPN server that allows incoming VPN connections (OpenVPN, WireGuard, PPTP, and IPSec etc.) While connected to the VPN server on the Archer BE3600, every other LAN device is accessible except for any that are mapped to use the VPN. This happens regardless of the type of VPN connection established on the Archer BE3600.
