Tether wifi not sharing internet

[tvrulesme]

I am running Debian GNU/Linux 8.9 (jessie) on a raspberry pi. I have a requirement to tether the wifi of this so that for instance I can pair openload from the same network.

My OpenVPN config is working fine and I can access the internet from the pi itself but I have no internet access when I connect to the tethered wifi using my phone. Can anyone spot something I am doing wrong:

Code: Select all

sudo sysctl -p
net.ipv4.ip_forward = 1

OpenVpn is running

Code: Select all

service openvpn status
● openvpn.service - OpenVPN service
   Loaded: loaded (/lib/systemd/system/openvpn.service; enabled)

 Main PID: 1325 (code=exited, status=0/SUCCESS)

and I can connect to internet

iptables have the following rules applied

iptables -A FORWARD -i tun0 -o eth0 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i eth0 -o tun0 -j ACCEPT

resulting in

Code: Select all

iptables -L

ACCEPT     all  --  anywhere             anywhere            

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination     

tether the wifi which I can see and connect to using my iPhone

Not sure if this helps but I do see the following conman errors
