The ATM Signaling Filtering Gateway

The ATM Signaling Filtering Gateway is a software allowing you to:

Filter ATM connections following the UNI 3.1 specification according to a Signaling Access control Policy Description which can be expressed through a very simple language.
Masquerade your internal ATM addresses by replacing outgoing connections source addresses by an address of your choice.

In order to use this software you need the following software/hardware:

Two SUNWatm ATM S-Bus NICs.
SUNWatm v1.0 or v2.0 drivers. These drivers can be retrieved from the SUN web site
A SUN Workstation running Solaris with two S-Bus idle slots.

This is experimental software. There are known bugs and certainly even many more yet unknown problems. This software has only been tested with SUNWatm v2.0 and SUNWatm v1.0 drivers.

Use at your own risk.
