Hi All, apologies in advance for what is probably a foolish error, but I'm hoping your wisdom can help me spot, or troubleshoot it.
Have re-setup OpenVPN on Raspberry Pi following SD Card failure, and can't get it to work. Followed excellent guide on
http://readwrite.com/2014/04/10/raspberry-pi-vpn-tutorial-server-secure-web-browsing which I used last time.
LAN IP of my Pi is 192.168.1.215
Server.conf:
local 192.168.1.215
dev tun

port 1194
ca /etc/openvpn/easy-rsa/keys/ca.crt

To eliminate issues with router port forwarding I've created an internal OVPN profile to test within my network first:
client
dev tun
proto udp

resolv-retry infinite

-----END RSA PRIVATE KEY-----

<tls-auth>
-----BEGIN OpenVPN Static key V1-----
-----END OpenVPN Static key V1-----

I've created a firewall opening script:
#!/bin/sh
iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o eth0 -j SNAT --to-source 192.168.1.215
This is chmod 700 and chown root
Finally, I've called this script from my /etc/network/interfaces file:
source-directory /etc/network/interfaces.d
auto lo
iface lo inet loopback
iface eth0 inet manual
pre-up /etc/firewall-openvpn-rules.sh
allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
All I get is the following in the client logs:
2015-12-03 16:19:06 LZO-ASYM init swap=0 asym=0
2015-12-03 16:19:06 EVENT: RESOLVE

2015-12-03 16:19:16 EVENT: RECONNECTING
Any and all assistance as to where I have gone wrong - or tips for how to track down the problem greatly received.
Thanks
Martyn.
