I have just installed ADSL and I need to firewall myself.
What I have:
1. Win 2000 server connected to ADSL modem on one NIC and rerouting to local network on another NIC
2. Hub for local network
3. 4 Win XP computers running on the network
4. Cisco 800 router currently not used
The only role of Win 2000 is to connect to ADSL and share the access
How can I best protect the network? Can the Cisco router be of any use? or should I go for Linux?
