How i got DNS and DHCP working

[ghostlywind]

After many hours of frustration and a couple dozen reflashes i finally got DHCP and DNS working on my FON

When karma is turned on it will show everything including IP.

I have a FON 2100 and am using digininja's firmware located here: Digininja firmware

If anyone has suggestions on making my setup better i would greatly appreciate it.

I hope this helps anyone who is having troubles like i did.

Thats pretty sweet! so did you flash it/ not like how it went/ and then re flash from beginning to end with jasager?

When i first tryed to get Jasager working i was using the kamikaze 8.09 and digininja's madwifi packages would keep crashing when i tryed to turn ath0, so i gave up but when he released his own firmware and everything was working everytime i tryed to set up dhcp and dns to get an IP on Jasager i would get errors. I started doing research on the openwrt forums and got it so i could an IP in Jasager but no internet to the wireless clients. I started more research and found out i need iptables to direct internet to the wireless. The reason i had to reflash so much is that when i try a new setting sometimes i wouldn't be able to get access to my FON after rebooting it and i learned backup config files when they work it cuts out a lot of time.

I just flashed the new Piranha 2 + Jasager 2.1 image.

then I scp'ed the files you list above ( after doing a copy and paste from the website to a text file )

I made sure to copy everything except the firewall.users file to /etc/config

and the users file to /etc

My Jasager is accepting connections, and issuing ip address, but the clients can not reach the internet.

I have my mac laptop set to ICS my Aircard with my ethernet. ( I changed the ICS network to 192.168.2.1 since

that's what macs use for ICS. )

The clients are able to use DNS, but when I tried to ping www.google.com for example,

the DNS resolves to the IP but it says Dest Port not reachable ( 10.10.10.1 )

say my client is 10.10.10.232, I am able to ping 192.168.2.250 ( the FON Eth0 interface )

and I can ping 192.168.2.1 ( the Laptop Ehthernet Interface )

Also from SSH on the fon, I am able to ping www.google.com.

so it seems to me I have a problem in the Fon, but i'm unable to figure out what it is.

Any thoughts??

is there a typo in the above configs? or is something changes with the new Piranha 2 + Jasager 2.1 ??

[cyoung_mi]

Hmm.. does anyone have any suggestions at all??

I'm really stumped here..

The clients are unable to reach the internet. Yet I can from the Fon unit.

What am I doing wrong?? Please??
