It may also be possible to run a capture directly on the router and let it store it into a file (many of them allow this, albeit most of them have storage space limitation so you can only capture short periods of time) or, instead, to send you a copy of the traffic matching a capture filter encapsulated into UDP packets with a special header (this is what e.g. If, however, both your PC's VPN address and the two remote devices are in 10.11.0.0/16 subnet, your chances are higher if you can convince the virtual switch at the remote end to send a copy of the traffic between the two devices to your VPN interface's virtual MAC address. In this case, your chances for direct capture are very low because there is a routing between the two subnets. You haven't provided your topology, but I assume that your PC has a normal internet connection and a VPN interface which gets an address from the 10.11.7.0/24 subnet while the devices you wish to capture are in 10.11.27.0/24 subnet. That depends on what exactly means remote.
