sslstrip on OpenWRT (Linux) wireless router

Router with Linux and Python

    I have a Buffalo WZR-HP-AG300H which I really like
    I used OpenWRT version r29484

Sufficient space for all the software (you may need an external drive/share mounted)

    My setup uses 11MB for OS, Python, and sslstrip

Sufficient RAM on your router

    My router has 128MB. Probably need at least 16MB

sslstrip python program by Moxie

    I had to use version 0.8 due to bugs in 0.9
    I didn't use the OpenWRT repository version because it was only version 0.6

iptables

    For OpenWRT I installed all the iptables packages (which includes modules) and the kernel (kmod-ipt) modules
    A package search on "ipt" should get you them all

Extract the sslstrip tarball to any directory you like

    I didn't separate it into the system or run the installer. I just used the stand-alone version.

Start it with python sslstrip

    Just the defaults. Use -h for other choices

Set your iptables to redirect all HTTP (port 80) traffic to sslstrip

    iptables -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 127.0.0.1:10000
    I tried using -j REDIRECT, but my version of OpenWRT didn't have it compiled. The above is just the long form of it anyway.

Bring up the login page for a site like Facebook
Enter in login credentials (fake if you want)
Look in the sslstrip.log file for the credentials
