setting up proxy server to share DSL for a small LAN

[kss]

Just installed aDSL line on my Windows NT server 4.0 (working) and than I setup the Proxy server on the client side through internet explorer browser. In the browser I went to Tools menu than internet options, clicked the Connections Tab and in Lan setting I enabled ONLY the proxy server and entered the IP address of the computer on which the ADSL is installed and set the port to 81 (Is the port necessary). But it doesn't work or open any sites. On which the DSL was installed I had one NIC connected to the internet and the other one to LAN and when pinged from either side they both reply. Someone please Help ! Why is my setup not working is there someting I'm missing. Maybe there is something I have to do on which the DSL is installed.

Well first do you have Microsoft's "Small business server", which includes the Proxy server service? The setting your configuring in IE configures IE to look for a proxy server "service" at the port of the choosen computer. If you don't have a proxy program running on that computer , then it won't work.

I don't know off the top of my head how much you would have to pay for the Proxy server program. ( either Proxy server 2 or ISA server) Depending on your budget you may have to go with some other option.

Probably this could help you. I have a 3 pc network at home; a laptop, a AMD and a 486 acting as a server conected to the DSL. I installed a Proxy server software called wingate in the 486 and wingate client software in the laptop and the AMD. It can work also as a firewall. You can get the trial version from their webpage (http://wingate.deerfield.com/).
If you dont want to pay for the software you can also get other proxy server software in the net, there are plenty of them; I would recommned you to use Wingate.

Good Luck! Venkaya

Be careful with Wingate. It is a very good program used by alot of people, but it has a few security holes/ bugs and is a favorite target of Script kiddies.

KSS: Try installing wingate at least to see if that can solve your problem, and after that try to get other proxy software.


**I havent had any bad expericence with wingate so far, but prevention is the clue to avoid future problems. Do you have other proxy software in mind that you could recommend?

thanks in advance

Sorry, but the only other proxy software I know of ,besides MS Proxy server and Wingate, is Novell's Bordermanger.


Wingate is well know to the script kiddie community who try to use a misconfigured proxy to "bounce" their web connections off of. Also Wingate can let people in to your internal network if misconfigured. So if you run one of these make sure to configure it correctly and watch for patches as there are many tools that scan for Wingate/SOCKS proxies.

Another option is to go out and get a broadband router. There are many good ones available for under $150.00 Personally, I use the Netgear 4-port DSL Router. I plug the DSL into the Netgear, configure my IP settings in the Netgear, and then set it up as the DHCP server on my network. Then the other 3 machines on my network connect to the router and are assigned an IP on a private IP schema.

One of the best reasons (IMHO) for using a router is that many of them will allow you to filter packets, which provide an extra level of security. I also have ZoneAlarm firewall and Innoculate virus protection running on all of my machines. Maybe I'm paranoid, but I've yet to be hacked or infected by any of those nasty virusse that have sprung up in the last year.
