I've got my FIOS router currently proving wifi, I bought a raspberry pi 2 to add a second AP with DHCP in a different area in the house to fill a strength void. (I don't mind having the fios router server 192.168.1.1-150 and the raspberry server 192.168.1.151-250 - or a separate range).
I can connect to the wireless part of it but it won't ping out anywhere. I've got the following in my udhcpd.conf file
start 192.168.42.1 #default: 192.168.0.20 end 192.168.42.200 #default: 192.168.0.254 interface wlan0 #default: eth0 remaining yes opt dns 220.127.116.11 18.104.22.168 option subnet 255.255.255.0 option broadcast 192.168.42.255 opt router 192.168.42.1 option lease 864000 # 10 days of seconds
This is my /etc/network/interfaces file. auto lo iface lo inet loopback
iface eth0 inet manual iface wlan0 inet static address 192.168.42.1 netmask 255.255.255.0 gateway 192.168.1.15 up iptables-restore < /etc/iptables.ipv4.nat
And lastly this is my iptables.ipv4
