broadcast to router
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?
i also have an ath9k wireless cardCode:eth0 Link encap:Ethernet HWaddr e0:cb:4e:44:f3:83 inet addr:192.168.1.100 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::e2cb:4eff:fe44:f383/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1219 errors:0 dropped:0 overruns:0 frame:0 TX packets:1140 errors:0 dropped:0 overruns:0 carrier:23 collisions:0 txqueuelen:1000 RX bytes:818864 (799.6 KiB) TX bytes:105753 (103.2 KiB) Interrupt:19 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:425 errors:0 dropped:0 overruns:0 frame:0 TX packets:425 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:33368 (32.5 KiB) TX bytes:33368 (32.5 KiB) usb0 Link encap:Ethernet HWaddr fa:f5:7a:37:17:9a inet addr:172.20.23.XXX Bcast:172.20.23.255 Mask:255.255.255.252 inet6 addr: fe80::f8f5:7aff:fe37:179a/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:3056 errors:30 dropped:0 overruns:0 frame:30 TX packets:3988 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:1983935 (1.8 MiB) TX bytes:675978 (660.1 KiB)

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?
Sometimes, real fast is almost as good as real time.

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:
iptables:Code:config_usb0=( "dhcp" ) config_eth0=( "192.168.1.2/24" )
router (linksys wrt120n):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
starting services:Code:Internet Connection Type [] DHCP [x] Static IP [] PPPoE [] PPPTP [] L2TP [] Telstra Cable Internet IP Address: 192.168.1.1 Subnet Mask: 255.255.255.0 Default Gateway: 192.168.1.2 DNS: 208.67.222.222 Local IP Address: 192.168.1.1 DHCP Server [x] enabled Start Address: 192.168.1.100 Max 50 Users Range: 192.168.1.100 - 149 Routing Table: Dest IP Subnet Mask Gateway Interface 0.0.0.0 0.0.0.0 192.168.1.2 WAN(Internet) 208.67.222.222 255.255.255.255 192.168.1.2 WAN(Internet) 192.168.1.2 255.255.255.255 192.168.1.1 WAN(Internet) 192.168.1.0 255.255.255.0 192.168.1.1 LAN & Wireless 127.0.0.1 255.255.255.255 127.0.0.1 Loopback
still, computer B can't access the internet and the "web" light on the router is not litCode:/etc/init.d/iptables start /etc/init.d/net.usb0 start /etc/init.d/net.eth0 start
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.
