I'm too much newbie, I know how does work any ADSL router, but i don't know how does work the cable modem stuff, here's my doubt, I have a webstar cable modem, 1 hub , 1 machine that's works as a router or server for my LAN which is windows NT, the first time my ISP put the cable modem, the server Win NT was able to see from outside only the server not the rest of machines of my private LAN, but now they came again, and configure all. now no one of my machines can be able to see from outside, ok I don't want my windows NT from being see from outside, instead I have 1 Box whit Slackware 9.1 on it. I have Apache, Mysql, Php, and stuff. Well the case is, i don't know how a cable modem works but I want to know any tips or something that make me feel possible to make my Slackware for be a personal web server and people from outside could see my web pages. how do I do that, I don't know if i have to enter some configuration in the cable modem to open ports or make my slack box DMZ, or how supposed to do it. My slack box use an static Private IP, and I'm connected trough the LAN whit and Ethernet Card, I already call My ISP to get some help, but they refused anything of my request, so I'm desperate to know something for where i could start.

Alright, Here are some possible answers to your cryptic post.
- your cable modem, unless it is a combination router/cable modem, probably has little to do with this issue. The cable modem simply allows your network to communicate with your isp, nothing more, nothing less (in most cases)
- the windows NT machine that works as your router for the network will need to be configured to pass requests on port 80 to your slackware box.
-If i was you, what I would do, is go to a local shop such as circuit city, or best buy, and get a router/firewall for about 50 bucks. I wouldnt want to have any Windows machine acting "as if " it was a firewall. Then you could pass port 80 on through your firewall/router to your web server. In addition to having your boxes tightened up on the network, this should provide a good level of security for you.
-alternatively, you could use your slack box as your firewall using iptables. This would be a good opportunity to learn how to use firewall and routing features in linux. Plus, I know i would feel more safe with my linux box exposed to the world than with a windows box. Also, if you were going to be putting your slackware box in a DMZ, then you would have to go through the iptables step and a hardening porcess anyhow, so you might as well make the switch.
-either way, you should also look at hardening you box. This is covered extensively in the security forum.
Do a search here on these topics, i know it has been covered extensively in the networking and our security forums.
side note; I wouldnt expect much in the way of support from your ISP. Your issues are related to networking, not connectivity. They are responsible for getting you an internet signal and possibly configuring one computer (usually only windows is officially supported) for that connection.
Yes, I probably would love to make my slackware the router of my network, but the problem is my ISP doesn't support Linux, in fact they only know how to deal whit windows, I still hating the idea of been behind a windows server as my server for the LAN. but I can't do anything. I supposed that yes my windows NT and cable modem work as cable Modem and router too, So if my windows Box is my router I supposed i have to open ports or make NAT in there that points to my Slack Box. I don't know how to open ports in windows I know how works in Linux, guess I have to interact more whit windows, I will get a manual of that,Regards by the way :P
