[bitfolk] Making OpenVPN routing settings survive a reboot

Following the recent upgrade and reboot of my Bitfolk server, OpenVPN had stopped working. (I don't use it very often on that server; hence I hadn't noticed.) After some trying, the issue turned out to be that the server had stopped functioning as a router - I thought I'd share what I did to make it work, in case others run into the same problem. I ran echo 1 > /proc/sys/net/ipv4/ip_forward modprobe tun iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j MASQUERADE /etc/init.d/openvpn restart Not sure if all of these were needed - the iptables one definitely was as that was the one that fixed it. Is there an easy way to make these changes permanent so that they will survive a future reboot? Thanks Martijn.
