    hi
    i connect to the internet using my phone (/etc/init.d/net.usb0)
    i want to pipe this connection from my computer into a router and broadcast it

    how would i go about doing this?

    A 56k connection? I think you'd need to get a wireless router/modem that accepts 56k. This unit will do that:

    There may be cheaper ones out there. Google: 56k wireless router.

    Are you saying that you want to share your modem connection with local computers via WiFi?

    by phone i mean smartphone (android htc eris) 3g network
    it's tethered to my computer via usb0

    this is what i'm aiming for:
    computer b (wlan0) -> router (eth0) -> computer a (usb0) -> phone -> internet

    computer a uses net.usb0 to connect to the internet through the phone
    i want to pipe this connection to the router via eth0
    the router then would broadcast the signal and computer b would connect to the router via wlan0

    Here is everything I've tried:
    /etc/conf.d/net:
    Code:
    config_usb0=( "dhcp" )
    config_eth0=( "192.168.1.2/24" )

    Code:
    iptables -F
    iptables -t nat -F
    iptables -P INPUT ACCEPT
    iptables -P OUTPUT ACCEPT
    iptables -P FORWARD DROP
    export LAN=eth0
    export WAN=usb0
    iptables -I INPUT 1 -i ${LAN} -j ACCEPT
    iptables -I INPUT 1 -i lo -j ACCEPT
    iptables -A INPUT -p UDP --dport bootps ! -i ${LAN} -j REJECT
    iptables -A INPUT -p UDP --dport domain ! -i ${LAN} -j REJECT
    iptables -A INPUT -p TCP --dport ssh -i ${WAN} -j ACCEPT
    iptables -A INPUT -p TCP ! -i ${LAN} -d 0/0 --dport 0:1023 -j DROP
    iptables -A INPUT -p UDP ! -i ${LAN} -d 0/0 --dport 0:1023 -j DROP
    iptables -I FORWARD -i ${LAN} -d 192.168.1.0/255.255.255.0 -j DROP
    iptables -A FORWARD -i ${LAN} -s 192.168.1.0/255.255.255.0 -j ACCEPT
    iptables -A FORWARD -i ${WAN} -d 192.168.1.0/255.255.255.0 -j ACCEPT
    iptables -t nat -A POSTROUTING -o ${WAN} -j MASQUERADE 
    /etc/init.d/iptables save
    router (linksys wrt120n):

    starting services:
    Code:
    /etc/init.d/iptables start
    /etc/init.d/net.usb0 start
    /etc/init.d/net.eth0 start
    still, computer B can't access the internet and the "web" light on the router is not lit
    this leads me to believe i'm not using iptables correctly (or incorrect router settings)
    i'm pretty sure the router is capable of this, since i've used it as a network switch in the past (internet -> router a -> router b -> LAN)

    Sorry to take so long to get back to you. What I do is to set up the phone into a WiFi hotspot mode instead of teathering it. That way, up to 5 devices/computers can access the internet using the phone as a WiFi access point and bypass the router altogether. You can set up the computer it is teathered to as a router, but in that case you probably need to reconfigure your regular router so that it routes gateway packets to the tethered system.

    i found using the wireless tethering heated up the battery and drained it extremely fast. i ended up wired tethering to the computer, ip masquerading using it as a router, broadcasting the signal via wlan0 ad hoc mode

    Glad you seem to have resolved your problems. The Android phones are flexible little buggers, aren't they?

    BTW, I think you can connect the phone to your computer USB port (without activating tethering or data mode - just charge mode), and still use it as a WiFi hotspot. The USB connection will keep it charged.
