l7-filter

We are configuring a linux box that will act as internet gateway for an office of 30-50 computers. We are using iptables/HTB for traffic shaping.

Is there a way to match traffic on L7 level? It's easy to identify traffic by TCP/UDP ports (like SIP and HTTP). But what if we are dealing with Skype & BitTorent?

It was surprise for me that there is no powerful and matured sulution for tasks like this. I found only l7-filter (http://l7-filter.clearfoundation.com/) patch for the Linux kernel, but it's no longer supported (it seems to). Moreover it couldn't be compiled with modern Linux kernels.

The only option I found was to use a Cisco router.

Are there other ways to identify and shape Skype and Bittorent traffic?
