Thank you Jason. Your response is very appreciated along with your work on the wireguard project. 1. Is there a minimum version of iproute2 that is needed? 2. Can that be mention in the dependency. 3. I installed from source and from the suggested rpm method at https://www.wireguard.com/install/ would it be possible to check for version for iproute2 and fail with a error message, Regards, Vikas -- VK On Wed, Apr 18, 2018 at 2:10 PM, Jason A.
