Hello,

I'm trying to set up a start-up script for AFWall+ currently using this one
 

cat /data/local/iptables-on.sh                 <
## IPtables On Script
## iptables -L
## iptables -S
## iptables -L -t nat

I don't get why Eddie is failing to connect - without this script it works flawlessly..
Would really appreciate your input.
