A heplful document but how do I configure the remote computer to receive the pcap?

Hi,

 

You have to take care of the following after configuring the controller as shown above.

 

1. The Controller should be reachable to the destination IP 

 

2. You should run packet capture ( Wireshark) on the destination

 

3. As the client traffic hitting the controller over GRE filter the packet capture with GRE
