• Some users have recently had their accounts hijacked. It seems that the now defunct EVGA forums might have compromised your password there and seems many are using the same PW here. We would suggest you UPDATE YOUR PASSWORD and TURN ON 2FA for your account here to further secure it. None of the compromised accounts had 2FA turned on.

Automatic HTTP Redirection Scenario

I’m wondering if the following scenario is possible to setup on a local network. All the computers in my home network are connected to single machine that acts as a server. This server is currently running WinXP, Apache and is sharing an internet connection with the other machines.

What I would like to do is redirect all HTTP requests from the client machines to a webpage locally hosted on the server. So, if a client attempts to enter an IP or enters a domain name in their browser, they will be taken to a webpage of my choosing on the server machine.

I’m not sure how to exactly accomplish this. Do I have to reroute all DNS lookups? If so, do I need my own DNS server running on the server? I would appreciate your help in this, and please bear in mind that I only have a rudimentary knowledge of network administration, enough to be able to setup a home network, enable internet connection sharing, file sharing etc. Thanks
 
Do a google and forums search for "captive portal." It's been discussed quite a bit in this forum. One method of accomplishing this is certainly through DNS rerouting. Otherwise, you'll have to implement firewall rules to redirect traffic to a proxy server, and have a proxy server running that can intercept these requests and return them to the client. It's very possible on linux, but with Windows you're going to have a hard time implementing these rules, especially with ICS.

It's also in the security thread stickied at the top of the forum :)

And since I have a free minute...
