I have the following setup:
- I have setup a Layer 3 Switch with multiple VLANs
- Multiple devices are connected to it on different VLANs via untagged access ports
- There is also a router connected to the switch which provides internet access (not part of a VLAN)
- A special access device is also connected to the switch over a trunk port. This device has multiple tagged (virtual) interfaces allowing it to communicate to all devices on all different VLANs. It uses Windows 10 as the operating system.
- A remote device is connected via VPN tunnel to the access device. It uses TeamViewer VPN.
Now the problem is on the remote device I can't ping any of the other devices (Device B, Device C). As per my understanding of VPNs, I should now be able to access those devices. I can ping Device B and Device C if I directly log in to Device B, but not on the Remote Device, however I can establish a TCP connection to tools running on Device A, so the VPN works.
I checked the routing table on Device A, but it seemed OK to me. I also enabled the "Route and Remote Access" service on Windows 10, but still no success.
Does anybody have some tipps or ideas what I could have missed? I am no network expert so I would greatly appreciate your help. :)
