GNS3 – 0.4.1
GNS3 is not a simulator, it is an emulator. This brilliant software allows you to emulate real IOS images in order to create a full-working lab environment.
Since version 0.4 you can emulate 1700 routers and PIX Firewalls! 
Version 0.4.1 has the following improvements/bugfixes:
- Corrected “Manual connections” which was broken.
- Moved the option to change a console port in the contextual drop-down menu.
- Some unicode errors have been corrected.
- Avoid to put default iomem and exec_area in .net files.
- Prevent to rename a connected firewall because pemuwrapper does not support removal.
- Check if links are connected to a slot before changing it.
- A new language: Polish.
- Added the possibility to automatically copy a base flash for PIX devices.
- Connections to external hypervisors was broken.
- Added a default RAM setting and a link to check the minimum IOS RAM requirement in IOS images window
