Jator,
I recently got the LinkSys DSL/cable router/4-port switch. It's so much better than ICS and Win2KPro. ICs was a bit flaky, one day the network just stopped working, had to reconfigure the whole thing. Then CompUsa ran a $20 off promotion along with a $30 LinkSys rebate, bringing the cost down to $99 🙂 I pulled a Russ (whipped out the CC and bought the sucker) in a moment of weakness. 😉🙂
Now my network is back to stealth mode, and things are working well. One thing neat about it, it allows a tunnel setup to allow 1 PC outside the network for webhosting, ftp, etc.. 🙂
I don't know what you are using for a firewall, but I had to drop the Internet security to medium to get ICS to work with ZoneAlarm (most recent free version). Network ports were closed not stealth in that setup.
Good luck getting that network going! 😀
