Jasager With Dnsmasq Problems

[Blackenz]

Hi there! I've looking in the forums the reason to my problem, but once i couldn't find anyone with this problem, i decided to post this question. So i installed Jasager on my fonera, and configured the dnsmasq as a DHCP server, (also edited some init scripts to automatically start the wireless interface and karma), but something strange is happening. When a client tries to connect to the jasager, the jasager sees de DHCPDiscover packet and replies with a DHCPOffer, but the real problem is that there is no DHCPAck on the client side. I tried this with different clients, but the problema remains... I am leaving here the configuration files so that anyone can spot any problem.

/etc/config/network

config 'interface' 'loopback'
	option 'ifname' 'lo'
	option 'proto' 'static'
	option 'ipaddr' '127.0.0.1'
	option 'netmask' '255.0.0.0'

The setup i am trying to configure is something like jasager (lan: 192.168.0.2, wifi: 192.168.0.3)-> BT5 MITM(lan: 192.168.0.1) -> Internet router

I believe i am not missing anything, in any case just ask.

Thanks ;)

You should have your LAN card hooked to the Fon/Jasager/Pineapple on a different network than the internet router.

Here is my setup guide I did to build a V1 Pineapple after I purchased the FON2100

Here is a diagram I made at the same time to explain my setup of what my typical setup is.

I have posted this many times on the forums... You need to level up your searching skills ;)

The internet router is on a different subnet than the lan card that is hooked up to the jasager (192.168.1.x internet router). Even with the ethernet cable disconnected, the jasager should be able to address a dhcp ip to a wireless client... I saw your tutorial, and my setup was based on yours, but maybe the problem is in the dnsmasq config file. I searched for this problem here, and saw no one with this, that's why i asked ;)

[Mr-Protocol]

I will add it to my google doc to avoid confusion when I get time to fire up the pineapple again.

With the dnsmasq config file, i meant the /etc/config/dhcp. I guess i'll be flashing the fonera again... Dumb resolution, but probably the best way... Just can't understand the dhcpdiscovery -> dhcpoffer but no dhcpack... ;)

[Mr-Protocol]

Ok, check my google doc again. I see you are but refresh it. I have added more of the config files mine has.
