Ok, so this is what I want to do

pfsense 192.168.1.1
WAN PPPoE
LAN Wireless Access Point 192.168.1.5
OPT1 Xbox 360 192.168.1.20
Open Ports 88 UDP 3074 TCP/UDP on 192.168.1.20

I could just buy a switch but since I have no computers with wired
connections other then my 360 seems like a waste.
Ive bridged OPT1 to LAN, and my Xbox 360 pulled an IP but I cannot
connect to the internet.
Can anyone help?
