OpenVPN Internet Takeover

So I've set up an openvpn bridging network in an attempt to create an openvpn network, and connect it to my wireless connection to connect other laptops. But running the OpenVPN start script.

#!/bin/bash

#################################
# Set up Ethernet bridge on Linux
# Requires: bridge-utils
#################################

# Define Bridge Interface
br="br0"

# Define list of TAP interfaces to be bridged,
# for example tap="tap0 tap1 tap2".
tap="tap0"

# Define physical ethernet interface to be bridged
# with TAP interface(s) above.
eth="wlan0"
eth_ip="10.0.1.2"
eth_netmask="255.255.255.0"
eth_broadcast="10.0.1.255"

for t in $tap; do
    openvpn --mktun --dev $t
done

brctl addbr $br
brctl addif $br $eth

for t in $tap; do
    brctl addif $br $t
done

for t in $tap; do
    ifconfig $t 0.0.0.0 promisc up
done

ifconfig $eth 0.0.0.0 promisc up

ifconfig $br $eth_ip netmask $eth_netmask broadcast $eth_broadcast

Do I need to give it a different ip area than my local network, or should I tell my router to reserve ips for this? The instant I run this script, conky no longer shows a local ip and I lose internet connection.
and Here is the output of ifconfig, connected to my network

My computer is behind a network, do I need to open any ports? I am going to use this network for multiplayer minecraft gaming, if that helps
