Arch Linux wireless access point -- need some help

Question

Hi everyone,
After yet another problem with my wireless gateway, I've decided to turn my old laptop into a router.
Setup:
1. Gateway
    Cable internet -> 4 IP's over ethernet
2. Laptop ("router")
    An old Compaq Presario laptop with RTL-8139/8139C/8139C+ ethernet and BCM4318 wireless card. It receives an IP from the gateway using dhcpcd.
Goal:
Turn laptop into a wireless router.
Accomplished so far:
1. Master mode on wireless card
    Used hostapd:
-bluemoon-16:13-~$ grep -v "^#" /etc/hostapd/hostapd.conf | grep -v "^$"
interface=wlan0
bridge=br0
driver=nl80211
logger_syslog=-1
logger_syslog_level=2
logger_stdout=-1
logger_stdout_level=2
dump_file=/tmp/hostapd.dump
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
ssid=bluemoon
hw_mode=g
channel=6
beacon_int=100
dtim_period=2
max_num_sta=6
rts_threshold=2347
fragm_threshold=2346
macaddr_acl=0
auth_algs=3
ignore_broadcast_ssid=0
wmm_enabled=1
wmm_ac_bk_cwmin=4
wmm_ac_bk_cwmax=10
wmm_ac_bk_aifs=7
wmm_ac_bk_txop_limit=0
wmm_ac_bk_acm=0
wmm_ac_be_aifs=3
wmm_ac_be_cwmin=4
wmm_ac_be_cwmax=10
wmm_ac_be_txop_limit=0
wmm_ac_be_acm=0
wmm_ac_vi_aifs=2
wmm_ac_vi_cwmin=3
wmm_ac_vi_cwmax=4
wmm_ac_vi_txop_limit=94
wmm_ac_vi_acm=0
wmm_ac_vo_aifs=2
wmm_ac_vo_cwmin=2
wmm_ac_vo_cwmax=3
wmm_ac_vo_txop_limit=47
wmm_ac_vo_acm=0
eapol_key_index_workaround=0
eap_server=0
own_ip_addr=127.0.0.1
wpa=2
wpa_passphrase=********
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP CCMP
rsn_pairwise=CCMP
This puts wlan0 into a Master mode.
2. Of course, hostapd required bridge
-bluemoon-16:13-~$ brctl show
bridge name bridge id STP enabled interfaces
br0 8000.0014a57528a6 no eth0
wlan0
Basically, I can associate with my newborn AP from another machine.
Problems:
DHCP.
More precisely, I can't configure dnsmasq to serve IPs. Everytime I run dhcpcd on an associated client machine,  I get a timeout. Here is my dncmasq.conf:
interface=br0
no-hosts
expand-hosts
domain=cr1520.fs.pa.us
dhcp-range=192.168.2.100,192.168.2.200,12h
Miscelanneous configs:
-bluemoon-16:15-~$ cat /etc/hosts
# /etc/hosts: static lookup table for host names
#<ip-address> <hostname.domain.org> <hostname>
127.0.0.1 bluemoon.localdomain localhost.localdomain localhost bluemoon
# End of file
-bluemoon-16:19-~$ cat /etc/resolv.conf
# Generated by dhcpcd from br0
# /etc/resolv.conf.head can replace this line
nameserver 192.168.1.1
nameserver 71.242.0.12
nameserver 127.0.0.1
search cr1520.fs.pa.us
# /etc/resolv.conf.tail can replace this line
-bluemoon-16:19-~$ cat /etc/hosts.{allow,deny}
# /etc/hosts.allow
exim:LOCAL
sshd:ALL EXCEPT 127.0.0.1
domain:ALL
# End of file
# /etc/hosts.deny
ALL: ALL
# End of file
I suspect that this something to do with my resolv.conf or /etc/hosts, by kinda lost...
TIA and Happy Christmas!

put your dhcp server and access point in the same subnet.
