NS-2 Network Simulator -- Help Needed!

[Ein]

Hey all,

I'm planning to use a network simulator for implementation of a project.
Someone mentioned that NS-2 is a good simulator, but he didn't know much about it.

At this point, I just need to know if it is feasable to use NS-2 for my project, which involves firewalling, & would greatly apprecialy anyone familier with it lending me a helping hand !

thanx in advance

NS doesn't do any networking. What I remember of it when i just hacked around with it is that its really good for studying stuff like routing algorithms, different flow control mechanisms and low level stuff like that. You might be able to simulate the effect of a firewall using it (i don't know if you exactly can, I have minimal experience in it) but you can't actually create a real firewall or any other thing such as that with it. Its a pure software simulator of networks.
