Cisco ASA is a hardware firewall appliance? there is no software Cisco firewall solution, you configure and mount the firewall (In from or beside your web server)

Thank you very much for your quick reply.

I have read the link you posted, but I m sorry I think you misunderstood my question. I was strugling with the amount of RAM and how many user lincenses are required for a Web server. Becuase I am not sure which firewall should i buy with how many user licenses and how much ram will be suitable for our web server with approximately 2000 hits per day.

Hope now I have clear my requirement.

User licences on Windows servers are not a problem for website connections
As for Server RAM - it depends on what else the Server is running? Web services don't have a great overhead, but if your running Databases that the web site uses on the same box then - you need more, also what version of server are you running? this will dictate how much memory can be addressed?

As for a firewall model - In you case Id suggest a Cisco 5510 with a security Plus Licence, then you can drop your Web server in a DMZ

Thank you for your reply.

It has given rise to another question in my mind and that is, the traffic is going to come to the webserver "first" then it will forward it to the firewall which in turn will forward request to the database and to the rest of the servers connected. Becuase in DMZ, normally an application server is kept in the middle of a webserver and database server. Am I right?

And What if I keep the webserver behind the firewall, will it effect the performance of my web application?

Thanks alot.

no the firewall is an edge device, Internet traffic comes to the firewall, then the firewall sends it to the web server, it does not matter to the firewall if the web server is behind(inside) or beside (in a dmz).

>>And What if I keep the web server behind the firewall, will it effect the performance of my web application?

I have clients with Very active web servers sat in a DMZ that talk to Databases behind the firewall and they get thousands of hits a day, the firewall introduces next to no latency in the web traffic.
