We have Small Business Server 2003 Premium. As we all know it has a built-in firewall-----ISA server.
I am wondering if we should buy a external firewall, for example, SOHO3.
The reason i am thinking about an external firewall is
1. the external firewall will be in charge of internet connection sharing, this will take some workload from the server.
2. the firewall will be a DHCP server, this will take some workload from the server.
3. if the server is down, all the workstations still have access to the net
am i correct? any thoughts based on your REAL field experience?
