Available modules

• TCP
• UDP
• ICMP
• SOCKS v4, 4a, 5
• HTTP CONNECT
• DNS (A/CNAME, PRIVATE, NULL) - Proof of Concept

Available versions
At the moment there are two different branches of the framework. The master branch is a somewhat stable version (v0.1) without the DNS module. The other branch is called next-version and that has the newer version (v0.2), which includes DNS support for a few records (A/CNAME, PRIVATE, NULL). This branch has not been tested thoroughly yet, please respect that before making an opinion about the source code and framework.
To have a somewhat stable release (without DNS), please use:

# git clone https://github.com/earthquake/xfltreat/

To get the DNS support from the next version branch (which was not tested thoroughly, please keep that in mind):

# git clone https://github.com/earthquake/xfltreat/
 # cd xfltreat
 # git checkout -b next-version v0.2

To configure DNS please check the DNS_notes.md.

Setup

# git clone https://github.com/earthquake/xfltreat/
 # pip install -r requirements.txt
 edit xfltreat.conf
 # server side: python xfltreat.py
 # client side: python xfltreat.py --client

Set up your linux box as a server
Enable IP forwarding as root by using either:

# sysctl -w net.ipv4.ip_forward=1

or

# echo 1 > /proc/sys/net/ipv4/ip_forward

then set up iptables to do the NAT'ing for you:

# iptables -t nat -A POSTROUTING -s 10.9.0.0/24 -o eth0 -j MASQUERADE

A few things to note

• python 2.7
• Linux only
• root privs needed

Side notes to expand

• server and check functionality can handle all modules enabled in the config.
• client should have only one enabled.
