Internet sharing and security

By mob_dream ·
Hello everybody
I have a small office contents from one server (win2003) with internet line (Leased Line) and public IP and 18 PC's as workgroup we work in web hosting so we need full internet access (ftp, messengers,.. etc) I used the RAS service (NAT & VPN) and every thing went OK but I found my server is not secure even my system coz I got errors massages and hackers left files for me.
for that could any one please tell me what is the best way to share my internet to clients with security.
and if possible how to manage the bandwidth (splitting( I want to control the bandwidth for the users.

Microsoft ISA Server is the perfect choice...
I has a Firewall & Caching Server fuctionality...
you can add as much access rules to protect your network and to control users access...
Also the Caching Server will save you alot of bandwidth...
As far as splitting is concerned i guess splitting your network into VLANs will do...

Hope that helps...

Cheers.

Another option for bandwidth control is to set up a QoS policy in euther ISA or on a router (which it seems you do not have). Setting up a router to NAT to your server would be a good idea. A static mapping would allow full access (as defined by you) to the internal network but supply some security by limiting unsolicited incoming connections to certain machines, and or to certain ports. Not to sound cheesy, but i just rememeber, my old Linksys I used at home allowd bandwidth splitting/allocating. It was a BEF41D I think. So a $50 router may be the solution.
