I have a TP-Link ML-MR6400 4G router and I want to create a VPN connection with my AWS VM. The scenario is that I have a sales demo unit that the sales guy takes on the road. Rather than require him to configure a local server for each demo, I want to have the complicated server on the AWS VM and he just plugs in his local device and 4G router and the device and VM can connect.
Local Device <> 4G Router <> Cellular Network <> AWS VM
I am using SoftEther on the AWS VM.
I have configured an IPSec tunnel between the local 4G router and the AWS VM.
I have been able to get the 4G router to show in its GUI that the VPN tunnel is up, but I can't get the devices to talk to each other.
Can anyone help me please? There is no configurable OS on the local device. It is a black box All that I can do is connect it to the 4G router and it will be given a local IP address.
The TP-Link 4G Router has the possibility to make itself the VPN Server (using OpenVPN) but for various reason I can't make the 4G Router the VPN server. I need it to be the client and for the AWS VM to be the VPN server.
I probably need to give you more information, but I'm not sure where to start. Thanks for your help!
