I need to use a firewall in order to protect a public network for accessing Internet. In my network, I have around 100-200 users and I want to allow them to use p2p software (like emule) although I would like to limit the bandwith and number of sessions of those connections. I know I can do it with an ASA firewall, and the number of simultaneous connections supported (that is one of the major problems with emule-like apps) is very high. I would like to use also the system to give VoIP capabilities to some of the users (less than 20) so I'm thinking of using a 2800 router instead of an ASA firewall.
The problem I have is that I'm not able to find the number os simultaneous connections supported by the diferent 2800 models, and I would not like to use a router that could be overloaded because of p2p traffic.
Can I use a 2800 router for this situation or do I need an ASA firewall?
Thank you for your help.
