[fzaynoun]

I need a good software package that emulate an entire network, i need simulation for routers, switch and firewalls, i need to be able to simulate VPN connection.  Wish is the best sofwares available to do this ?

There are multiple out there

OPNET, NS2 (open source), GNS3 (freeware). GNS has limitations on the images it can run.

I hope it helps.

Hi, I too am looking for a good Network Simulator to help me in my preparation for the CCNA certification and was hoping you could share with me what you have found out.

Thanks,

I would suggest to check dynamips and GNS3.

pkampana, thank you for the feed back I will look at both of these.  I have seen a lot of good ref. to the GNS3 and that it is Freeware which is nice as I am paying for my own education on this stuff.
