Hi friends !
I want to install ISA Server 2006 on Windows 2003 Server. I want this ISA to work as firewall and Web Caching Server. The network scenario is as following:
(ISP) 10.10.1.1---10.10.1.3 ( Fa 0/1) Router (Fa 0/0) 220.127.116.11---18.104.22.168 (Ext) ISA 172.20.0.1 (Int)---Internal Switches
The machine where I want to install ISA has following configuration. (Please tell me if the machine is strong enough to serve 500 users or not.)
Model : HP Compaq dc5100 MT (Multi Processor PC)
RAM : 1. Intel(R) Pentium(R) 4 CPU 3.40 Giga Hertz
2. Intel(R) Pentium(R) 4 CPU 3.40 Giga Hertz
HDD : SATA HDD with 80 GB Capacity ( I will attach one more HDD to keep cache and log files, give your opinion)
NIC Cards: 1. Broadcom NetXtreme Gigabit Ehternet (ISA External Interface<---->Cisco Router's FastEhternet 0/0 port )
2. Gigalink NIC Card (ISA Internal Interface<---->Internal Switch)
On Cisco Router, I have created a reflexive access list and it is working fine. Now, I want to configure ISA as software based firewall with web caching feature.
Please note that WEB CACHING FEATURE is very important for me to configure so that web requests for already cached web pages don't go to internet, thus enabling us to have fast internet surfing.
Please provide a suitable configuration (specially for web caching).
