Editing my openvpn-event file

[jackoboy9]

I want to edit my openvpn-event file (contents below) so that...

1. certain IP addresses (e.g. netflix.com) are not pushed through the VPN.
2. traffic from certain ports (e.g. port 35000) are not pushed through the VPN.

At the moment all it does is forward all the traffic from IP addresses between 192.168.1.2 and 192.168.1.127 through the OpenVPN client 3.

Thank you

#!/bin/sh

sleep 2

for i in /proc/sys/net/ipv4/conf/*/rp_filter ; do
  echo 0 > $i
done

ip route flush table 100
ip route del default table 100
ip rule del fwmark 1 table 100
ip route flush cache
iptables -t mangle -F PREROUTING

ip route show table main | grep -Ev ^default | grep -Ev tun13\
  | while read ROUTE ; do
      ip route add table 100 $ROUTE
done

ip route add default table 100 via $(nvram get wan_gateway)
ip rule add fwmark 1 table 100
ip route flush cache

iptables -t mangle -A PREROUTING -i br0 -j MARK --set-mark 1

iptables -t mangle -A PREROUTING -i br0 -m iprange --src-range 192.168.1.2-192.168.1.127 -j MARK --set-mark 0

exit 1
