Hi all, I have finally got a somewhat stable setup working after a lot of configuration issues. Here is what I currently have set up: From the cable modem I have the cat5 going to a (underpowered 500mhz 128 ram) Windows Server 2003 box, which has 2 NIC's attached to it and is running NAT for the internal clients. Hanging off that internal NIC on the server, I have my wrt54g set up to do DHCP for all of my clients, which are both wired and wireless. I am having no problem keeping the wireless computers connected but I do have about a 100 foot cable of cat5 running to my roommates Desktop and he is having trouble with his internet working, it "half works" in that it takes forever and soemtimes drops out randomly. If I use a 2 ft cable wired to the wrt54g I have no problem whatsoever so I am thinking that the two 100' UTP cables running side by side maybe are getting some interference somewhere along the way. When running a continuous ping test to google.com I occasionally get timeouts (5%) on that 100' UTP connected desktop. So that is my first issue, and my 2nd question is: Other than installing all service packs and updates for security, how best should I secure my server that is directly connected to the internet? I'm wondering if my server isn't already hacked... I have no firewall enabled on it currently... lol I want to know if there is a way to just have server2003 be my internet connection (reason being my ISP (comcast) only gives a wan ip to computers, not routers..... I know I'm pissed) then have my router do all the NAT and DHCP and configuration on the internal side of things. Basically having the server2003 PC be "invisible" to the router other than providing it with a gateway to the internet. ANyways, got to get to class sorry if I was unclear and rambled-- kind of in a hurry.
