Can you to use the vtun software (http://vtun.sourceforge.net/)
to udp ou tcp connections.
Features:
=========
VTun is the easiest way to create Virtual Tunnels over TCP/IP networks.
It support various tunnel types and provides many useful features:
- Encryption
- Compression
- Traffic shaping
VTun is easily and highly configurable. It can be used for various
network tasks:
- VPN
- Mobile IP
- etc
Tunnel Types
============
IP tunnel (tun).
Supports point-to-point IP tunnel.
Ethernet tunnel (ether).
Supports all protocols that work over Ethernet:
IP,IPX,Appletalk,Bridge,...
Serial tunnel (tty).
Supports all protocols that work over serial lines: PPP,SLIP,...
Pipe tunnel (pipe).
Supports all programs that works over Unix pipes.
Compression
===========
Deflate (zlib).
Very efficient compression. Supported for TCP only.
LZO (lzo).
Super fast compression. Supported for UDP and TCP.
Encryption
==========
Challenge based authentication.
No clear text passwords.
BlowFish 128 bits key.
Fast efficient encryption with 128 bits MD5 hash keys.
Traffic Shaping
===============
Platform Independent Traffic Shaper.
Allows to limit inbound and outbound speed of the tunnels.
Platforms
=========
Linux.
RedHat, Debian, Corel, etc.
FreeBSD and other BSD clones.
FreeBSD 3.x, 4.x, OpenBSD, etc.

This makes sense if you're a lawyer. ;-) They're trying to alleviate
anyone communicating anything away from the "company" that they can't
see.
At least that's what their attorney's told them to do. Then again,
maybe
this didn't happen at your former employer and they're just idiots.
personally I like the idea of using steganography to pass information to
the outside world via the graphics that make the web such a PITA to
work in knowadays.
