Debian As A Router [Not Assigning IPs]

I've been trying to set up an old desktop as a wifi router. I've looked at a lot of information online, but mostly this:

https://seravo.fi/2014/create-wirele...-point-hostapd

I've gotten where I can see the ssid from my phone and laptop. However, it starts to connect, but never receives an ip from the access point.

Here's what I have currently enabled in /etc/hostapd/hostapd.conf:

Code:

interface=wlan0
bridge=br0
driver=nl80211
logger_syslog=-1
logger_syslog_level=2
logger_stdout=-1
logger_stdout_level=2
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
ssid=GhettoNet
country_code=US
hw_mode=g
channel=7
beacon_int=100
dtim_period=2
max_num_sta=255
rts_threshold=2347
fragm_threshold=2346
macaddr_acl=0
ignore_broadcast_ssid=0
wmm_enabled=1
wmm_ac_bk_cwmin=4
wmm_ac_bk_cwmax=10
wmm_ac_bk_aifs=7
wmm_ac_bk_txop_limit=0
wmm_ac_bk_acm=0
wmm_ac_be_aifs=3
wmm_ac_be_cwmin=4
wmm_ac_be_cwmax=10
wmm_ac_be_txop_limit=0
wmm_ac_be_acm=0
wmm_ac_vi_aifs=2
wmm_ac_vi_cwmin=3
wmm_ac_vi_cwmax=4
wmm_ac_vi_txop_limit=94
wmm_ac_vi_acm=0
wmm_ac_vo_aifs=2
wmm_ac_vo_cwmin=2
wmm_ac_vo_cwmax=3
wmm_ac_vo_txop_limit=47
wmm_ac_vo_acm=0
eapol_key_index_workaround=0
eap_server=0
own_ip_addr=127.0.0.1

Here is what is currently in /etc/dnsmasq.conf:

Code:

interface=lo,wlan0
no-dhcp-interface=lo
dhcp-range=10.0.0.100,10.0.0.200,255.255.255.0,4h

I also have the following start up script for boot time as well:

Code:

#!/bin/bash

rfkill unblock 0

iptables -F
iptables -t nat -F

iptables -P INPUT ACCEPT
iptables -P OUTPUT ACCEPT
iptables -P FORWARD ACCEPT

iptables -A FORWARD -i wlan0 -s 10.0.0.0/255.255.255.0 -j ACCEPT
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

/etc/init.d/dnsmasq restart
/etc/init.d/hostapd restart

ifconfig br0 up

It appears this is a problem with dnsmasq or the br0 interface:

Code:

I should also note that I have already installed bridge-utils and rebooted. Any suggestions greatly appreciated.

EDIT: I found enabling "bind-interfaces" in /etc/dnsmasq.conf silenced the "DHCP packet received on br0 which has no address" message with /etc/init.d/dnsmasq status. However, still not getting any ip addresses...
