I compiled version 20170421 for my turris omnia running a modified OpenWRT OS. I was really happy to see, how well wireguard performed between my 2 routers compared to OpenVPN. But i consistently could reproduce a relevant error: after transferring about 280Mbyte over the wireguard VPN over a samba share, both my routers crash and restart. As far as i can tell, there is no memory leak (1 router has 1Gbyte of RAM, the other 2 Gbyte and they don't fill up during the process). Im not sure what information i could post, as no logs are written or how to debug this, but i'm more than happy to help out. I opened the respective Ports on the firewall.

#!/bin/sh
ip link add dev tun1 type wireguard
ip addr add 10.1.3.1/32 peer 10.2.3.1 dev tun1
wg setconf tun1 /etc/wireguard/staticfmf/conf
ip link set tun1 up
route add -net 10.2.0.0 netmask 255.255.0.0 gw 10.1.3.1

#!/bin/sh
