Just when I thought it worked here are more problems: The steps I followed were: 1. wget https://rpmfind.net/linux/fedora/linux/releases/25/Everything/x86_64/os/Packages/i/iproute-4.6.0-1.fc25.x86_64.rpm 2. yum install iproute-4.6.0-1.fc25.x86_64.rpm I installed from fc25 since rhel7 does not have an upgraded iproute package. 3. After installing the iproute 4.6 I do NOT get the error message: "Error: argument "suppress_prefixlength" is wrong: Failed to parse rule type" 4. ifconfig shows the wg0 interface. 5. After approx 2 minutes my ssh connection to the machine over the LAN (eth0) gets disconnected. 6. When I ssh back in to the machine, ifconfig does not show the wg0 interface.

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.
