dhcp3 issue with airbase-ng

[TAPE]

Nick & Gitsnik, thank you very much for your excellent comments and help !

I finally have it working.. thankfully, it was driving me nuts.. ;

>using a netbook with back|track 4 pre final
>wifi dongle WUSB54GC on netbook having internet access on wlan1

Created/configured the dhcpd.conf file as required and mentioned hereabove in Nick's post.

Then created tap interface

 
airmon-ng start wlan0
airbase-ng -e "TEST_AP" -c 9 mon0

Brought the tap interface up and assigned the necessary following Nick's post;

ifconfig at0 up
ifconfig at0 192.168.2.129 netmask 255.255.255.128
route add -net 192.168.2.128 netmask 255.255.255.128 gw 192.168.2.129

Followed Gitsnik's suggestion on the dhcp using the alternative file and alternative pid ;

mkdir -p /var/run/dhcpd && chown dhcpd:dhcpd /var/run/dhcpd

dhcpd3 -cf /etc/dhcp3/dhcpd.conf -pf /var/run/dhcpd/dhcpd.pid at0

Ran the iptables as advised ;

iptables --flush
iptables --table nat --flush
iptables --delete-chain
iptables --table nat --delete-chain
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables --table nat --append POSTROUTING --out-interface wlan1 -j MASQUERADE
iptables --append FORWARD --in-interface at0 -j ACCEPT
iptables -t nat -A PREROUTING -p udp --dport 53 -j DNAT --to 192.168.1.1

192.168.1.1 being my actual internet gateway.


And SUCCESS !

Was able to connect, get IP and surf around happily. DL speed not too brilliant at approx 65 KB/s however this expected and all good.

Thanks again guys for the assistance, all greatly appreciated !

Nick & Gitsnik, thank you very much for your excellent comments and help !

You should pronounce us Gitsnik & Nick. I am very "small" in front of Gitsnik.

Glad to hear you got it working.

Since I am using the same network address in my scripts, dhcpd.conf and iptable rules, you can download my script "how to: E-Z setup..." and look at the end of it. You will see how I handle traffic in several "modes" into BT4 box. You may found some useful informations there and do some advanced tricks in the future.

Well done.

Nick

I will definately keep looking at your script and look forward to see it developing as well !

When you get it fine-tuned it is going to be awesome indeed !

Thanks again for your help Nick, and dont worry, think most of us here are kinda "small" in front of Gitsnik

The provision of a simple, practical example in the face of my sometimes over-the-top theoretical comments is not to be discounted so easily!

Well done =TAPE=! Look forward to reading a blog post on the topic!

Come on Gitsnik, don't be so modest.

I was speaking for myself and I know that you know more things than me. There is no "over-the-top theoretical comments"

Maybe you don't know also that until today you are the only one how spend some time to respond to my BT4 related posts and I am thankful for this.

Let me make one compliment. I show some respect to your knowledge level.

Nick.
