Ive tried forwarding manually and with web gui, to no avail.

Ive spent probably 12hrs on this in the last two days. When i run Nmap i get port 80 is filtered. I connected directly to the host and can connect just fine.

here is the ouput i get:

Code:
root@DDWRT:~# iptables -t nat -vnL PREROUTING

SORTED

apparently i cannot view from my own ip, not really sure as to why, but ok. piggybacked all of my neighbors wifis and was able to access it just fine, for some reason if it originates from the host ip, it gets dropped. dont really care at this point as long as its accessible elsewhere, localhost works for me.
