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

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)
