That sentence refers to Step 3 in the tutorial.

The DHCP server runs on the Ubuntu PC. Then in Step 4 you configure the Fon router to get IP addresses from the DHCP server on your Ubuntu PC.

could you please clearefy for me where do you run the dhcp server?
Is in on the FON or on the UBUNTU PC.
I cant get it from the contex.

I asume it does not matter where you run it as long as the gateway the clients get is my laptop connection to the internet( correct me if I am wrong here)

If you’re interested in doing that, follow this tutorial (https://help.ubuntu.com/community/Upside-Down-TernetHowTo) except for the networking setup.

For that, kill firestarter because we’re using iptables straight up. Just save the following code as “iptables.conf”, use iptables-restore < /wherever/you/saved/iptables.conf to set up your firewall and you should be good to go.

*nat
-A POSTROUTING -j MASQUERADE
-A PREROUTING -i eth0 -p tcp -m tcp –dport 80 -j REDIRECT –to-ports 3128
-A PREROUTING -p all -d 192.168.0.1 -j DNAT –to-destination 192.168.1.1
COMMIT

*filter
:OUTBOUND – [0:0]
-A INPUT -i lo -j ACCEPT
-A INPUT -m state –state ESTABLISHED -j ACCEPT
-A INPUT -p all -s 127.0.0.1 -d 127.0.0.1 -j ACCEPT
COMMIT

I’m totally new at this, and it was a great learning experience. For those who are troubleshooting (like I was), here’s a few tips that helped me:

1. If you can’t access the Fon from the static IP in step 4, you’re not SOL. Just unplug it, add a host in GADMIN-DHCPD with the MAC address of the Fon and 192.168.0.250 and you’re good to go.

2. If you don’t have the web interface, you don’t need it. Just ssh into the Fon, and type “uci show” to see all the settings and “uci set =” to set them. If you really want the web interface, use Darren’s Tutorial (link at the top of this page) and use the opkg tool instead of ipkg to install it.

3. I couldn’t get the ICS working in Firestarter. I found an easy way around it by adding “routers: 192.168.0.1, domain-name servers: 192.168.1.1, and broadcast address: 192.168.0.255″ to GADMIN-DHCPD in the “Client Settings” section.

I hope those help you if you’re stuck and if not, make sure you did all the above steps in the guide correctly and check out the Hak5 forums. There’s a whole forum dedicated to the Jasager. Thanks again for this great guide!

I did and now it’s broken…

Not much on google about it..It uses digininja madwifi patches..

Will definately be using firestarter and gadmin-dhcp3..

thanks..

“to use the built in DHCP server in OpenWrt and let it handle the whole jasager-subnetwork”

If you are trying to reroute the network traffic through your computer so you can sniff it, then you need to make it (the computer) the DHCP server. The Jasager (OpenWRT) will query your computer’s DHCP server for an IP address to be issued to any wireless client that connects to it.

If you don’t want to channel the traffic through an external gateway, then the built in DHCP server will do. But then you will not be able to sniff the traffic.

If this did not answer your question, please clarify.
