Port forwarding not working?

    I have installed teddy_bear's Tomato ND USB Mod beta 10 and optware 9.5 on my RT-N16. I can access the setup page and built in FTP remotely using http://wanip:8082 and ftp://wanip:21 without any problem. However, after applying the following setting:

    On___Proto__Src Address___Ext Ports____Int Port____Int Address_____Description
    On___Both________________80___________________192.168.1.1_____HTTP Server
    On___Both________________8123_________________192.168.1.1_____Proxy Server

    I can access http://wanip:80 or http://wanip:8123 at home with computers connected to the router. But I cannot access those address remotely. Transmission works fine remotely even without forwarding port 9091.

    Can someone tell me whats happening?

    You can't forward directly to an internal port on the router without a corresponding ACCEPT rule (add to the Firewall scripts tab):

    iptables -I INPUT 1 -p tcp --dport 80 -j ACCEPT
    iptables -I INPUT 2 -p tcp --dport 8123 -j ACCEPT
