NAT Gateway by iptables dnsmasq

2011-01-05T17:10:00Z

Qleak: added bit about eth0<->usb0 tethering not in Freetether

The following guide can be followed on the palm to make a NAT gateway from a usb0 (tether) to ppp0 (EVDO). It is also possible this can be adapted to use a palm pre as a usb wireless adapter, that is NAT gateway from usb0 to eth0. Since wpa_supplicant and wireless tools are included with webos it is also possible that these could be adapted to build your own wifi hotspot from built in commands.

https://help.ubuntu.com/community/Internet/ConnectionSharing

For ppp0<->usb0 tehtering this is however an academic exercise as FreeTether does a fine job

http://www.webos-internals.org/wiki/Application:FreeTether

As of yet Freetether does not provide the facility to use your WebOs device as a wireless usb controller. That is, tethering eth0<->usb0

==Turn on USBnet on palm==
get a root terminal and enter the commands: This requires a reboot so exit anything you're doing on your phone.
<pre><nowiki>
usbnet enable
reboot
</nowiki></pre>

==Make dnsmasq.palm.conf check our config file (only do once)==
<pre>
mount -o remount,rw /
echo conf-file=/etc/dnsmasq.usb.conf >> /etc/dnsmasq.palm.conf
mount -o remount,ro /
</pre>

==Make dhcp/dns availalbe to usb0==
get root terminal and use the following to make dhcp/dns available to usb0
<pre><nowiki>
mount -o remount,rw /
echo interface=usb0 >> /etc/dnsmasq.usb.conf
echo dhcp-host=192.169.0.202 >> /etc/dnsmasq.usb.conf
echo dhcp-range=192.168.0.203,192.168.0.203,15m >> /etc/dnsmasq.usb.conf
stop dnsmasq
start dnsmasq
mount -o remount,ro /
</nowiki></pre>

==Make Sure usb is correct address==
Attach the usb cable between your computer and palm.
Run <pre>ifconfig usb0</pre> on your palm and make sure the IP is 192.168.0.202

<pre><nowiki>
ifconfig usb0 up
ifconfig usb0 192.168.0.202
</nowiki></pre>

Technically, you don't need this address but it sure makes it easier if you are using ssh to get your root terminal as this appears to be the default usb address :/

==A note on SSH root terminal==
novaterm users skip this step.

You'll want to connect to the root terminal from here on out using usbnet. So open your computers connection to the usbnet.

==Saving your initial iptables settings (optional)==
iptables is reset every time your palm is rebooted. But if you wish to save your iptables settings to avoid a reboot here is how.
<pre>
iptables-save -c > /media/internal/iptables.save
</pre>
==Setup packet forwarding to tether usb0 (cable) to ppp0 (EVDO)==
You will need to shut off wifi on your phone (it won't work otherwise). To do this tap on the upper left hand corner where the wifi icon is. Select "Wi-Fi" -> Turn off Wi-Fi

<pre><nowiki>
sysctl -w net.ipv4.conf.default.forwarding=1 net.ipv4.conf.all.forwarding=1
iptables -t nat -A POSTROUTING -o ppp0 -s 192.168.0.0/24 -j MASQUERADE
iptables -t nat -A PREROUTING -i ppp0 -p tcp --dport 3074 -j DNAT --to-destination 192.168.0.203
iptables -t nat -A PREROUTING -i ppp0 -p udp -m multiport --dports 88,3074 -j DNAT --to-destination 192.168.0.203
iptables -A FORWARD -i ppp0 -d 192.168.0.203 -p tcp --dport 3074 -j ACCEPT
iptables -A FORWARD -i ppp0 -d 192.168.0.203 -p udp -m multiport --dports 88,3074 -j ACCEPT
</nowiki></pre>

==Setup packet forwarding to tether usb0 (cable) to eth0 (Wi-Fi)==
Make sure your Wi-Fi is on and connected to an Access Point.

<pre><nowiki>
sysctl -w net.ipv4.conf.default.forwarding=1 net.ipv4.conf.all.forwarding=1
iptables -t nat -A POSTROUTING -o eth0 -s 192.168.0.0/24 -j MASQUERADE
iptables -t nat -A PREROUTING -i eth0 -p tcp --dport 3074 -j DNAT --to-destination 192.168.0.203
iptables -t nat -A PREROUTING -i eth0 -p udp -m multiport --dports 88,3074 -j DNAT --to-destination 192.168.0.203
iptables -A FORWARD -i eth0 -d 192.168.0.203 -p tcp --dport 3074 -j ACCEPT
iptables -A FORWARD -i eth0 -d 192.168.0.203 -p udp -m multiport --dports 88,3074 -j ACCEPT
</nowiki></pre>

==Setup your computer==

It may help to disconnect other network interfaces at this point on your computer (through network manager). If you used SSH to connect to your phone you need to disconnect the usb network connection (in the network manager not the cable).

On Ubuntu Linux 10.04 in network manager right click the icon select "Edit Connections". Find the wired interface probably named "Auto usb" edit and uncheck "connect automatically" box.

Windows / Mac instructions coming soon.

==Restoring your palm to it's original settings==
<pre>
sysctl -w net.ipv4.conf.default.forwarding=0 net.ipv4.conf.all.forwarding=0
mount -o remount,rw /
echo -n "" > /etc/dnsmasq.usb.conf
stop dnsmasq
start dnsmasq
mount -o remount,ro /
</pre>
===Restoring iptables (optional)===
<pre>
iptables-restore -c /media/internal/iptables.save
</pre>
==Trouble Shooting==
The following commands can hopefully give you and us an idea of what is going wrong. If you have difficulties please post the output of these with your phone carrier / phone model / webos version to http://forums.precentral.net/palm-pre/272021-pre-gateway-via-iptables-possible.html. For example
Verizon / Palm Pre / webos 1.4.5.

<pre>
sysctl net.ipv4.conf.default.forwarding net.ipv4.conf.all.forwarding

Sometimes there are extra routes floating around (maybe you forgot to turn off eth0 or usb0 sometimes makes an appearance). Usually deleting the route helps. Don't delete ppp0. Deleting eth0 or usb0 is safe. To fix eth0 cycle the Wi-Fi on the phone off then on.

===route===
Sometimes there are extra routes floating around (maybe you forgot to turn off eth0 or usb0 sometimes makes an appearance). Usually deleting the route helps. Don't delete ppp0. Deleting eth0 or usb0 is safe. To fix eth0 cycle the Wi-Fi on the phone off then on.

Qleak:

The following guide can be followed on the palm to make a NAT gateway from a usb0 (tether) to ppp0 (EVDO). It is also possible this can be adapted to use a palm pre as a usb wireless adapter, that is NAT gateway from usb0 to eth0.

==Shut of the Wifi connection on palm==
You will need to shut off wifi on your phone (it won't work otherwise). To do this tap on the upper left hand corner where the wifi icon is. Select "Wi-Fi" -> Turn off Wi-Fi

==Turn on USBnet on palm==
get a root terminal and enter the commands: This requires a reboot so exit anything you're doing on your phone.
<pre><nowiki>
usbnet enable
reboot
</nowiki></pre>
==Make dhcp/dns availalbe to usb0 (only do once)==
get root terminal and use the following to make dhcp/dns available to usb0
<pre><nowiki>
mount -o remount,rw /
echo interface=usb0 >> /etc/dnsmasq.palm.conf
echo dhcp-range=192.168.2.2,192.168.2.3,2h >> /etc/dnsmasq.palm.conf
stop dnsmasq
start dnsmasq
mount -o remount,ro /
</nowiki></pre>

==Setup packet forwarding==
<pre><nowiki>
ifconfig usb0 up
ifconfig usb0 192.168.2.1
sysctl -w net.ipv4.conf.default.forwarding=1
sysctl -w net.ipv4.conf.all.forwarding=1
iptables -t nat -A POSTROUTING -o ppp0 -s 192.168.2.0/24 -j MASQUERADE
iptables -t nat -A PREROUTING -i ppp0 -p tcp --dport 3074 -j DNAT --to-destination 192.168.2.2
iptables -t nat -A PREROUTING -i ppp0 -p udp -m multiport --dports 88,3074 -j DNAT --to-destination 192.168.2.2
iptables -A FORWARD -i ppp0 -d 192.168.2.2 -p tcp --dport 3074 -j ACCEPT
iptables -A FORWARD -i ppp0 -d 192.168.2.2 -p udp -m multiport --dports 88,3074 -j ACCEPT
</nowiki></pre>

==Setup your computer==

On Ubuntu Linux 10.04 in network manager right click the icon select "Edit Connections". Find the wired interface probably named "Auto usb" edit and uncheck "connect automatically" box.

Windows / Mac instructions coming soon.

==Trouble Shooting==
Make sure both these values are 1.
<pre><nowiki>
sysctl net.ipv4.conf.default.forwarding net.ipv4.conf.all.forwarding
</nowiki></pre>
Beware, the palms seems to like setting this to 0 whenever network settings are changed.
