I have a situation and need your comment.

Existing network setup consists of firewall and ISA server. The control is to allow or disallow users to access the internet through ISA server.

Planning is to remove the ISA server. Can a firewall allow and disallow internal users from accessing the internet as currently what ISA server is doing?

The reason is simple, we don't want to maintain OS and server. If firewall can do proxying, than we may want to do that.

Thanks.

Some can. As a minimum you'll need one that provides an http proxy with some sort of user authentication scheme in addition to being just a firewall. Of the top of my head you can do this with both Cyberguard and Checkpoint. The above, of course, will only give you control over your browsing. If you want to control everything destined for the internet that's going to be trickier. To do that with a firewall alone you'd probably need clients with fixed IP addresses but the administrative overhead and complexity would be silly. Hence things like ISA server!

To add what the Bishop said, ISA server is much more than a firewall. It performs has the functionality of a firewall, web caching and proxy server, bandwidth manager. It can also act as an application proxy for non-http protocols like SMTP. In addition, even though VPN functionality is built into Windows 2000/2003 server, ISA has a number of enhancements which make it easier to deploy VPNs.

I suppose your final decision will be influenced by how much functionality the replacement firewall possesses, and how much of the ISA server "extras" you really need.

Its worth also noting that the Bandwidth Management was dropped from ISA in ISA 2004 upwards because it didn't work properly in ISA 2000

Actually, it's back to a limited extent in ISA 2006.
