Resolved Question

How do I allow certain users/IP addresses access to website?

by Steve2294 / December 20, 2012 9:44 PM PST

I'll be up front, this is a question for homework help. I'm not asking for an answer (that'd be cheating), more like direction to where I can find an answer (or if I'm on the right track with my hunch).

I want to create a website but only allow a certain user or group of users access to that website. Assuming that user or users will be from the same location, and likely the same static IP, can I throw a firewall between my internet connection and web server and only allow that specific IP address access to my web server by a rule?

If there is a better way to handle that, I'd appreciate being pointed in the right direction. Thanks!

"the same location" is a problem. Many people use a laptop or a tablet or iPod or smartphone with WiFi or 3G to browse the net. And their IP-address is dependent on where they are. I don't even mention Internet cafe's and such where you can use the internet on their machines after a paying a fee, or using a PC at work, school or with friends or family.

So that's an assumption that only would be valid in a homework environment. Assuming it dates from before the days of laptops and tablets and iPod and smartphones and 3G and 4G, even then an IP-address wouldn't have been useful, because back in the days of dial-up connections, all dial-up connections had a dynamic IP-address. They gave you another address every time you dialled in. And even then there was work and school and friends and family where that 'certain group of users' could want to get access.

So any other way to handle this would be better than a way using the IP-address.

Thanks for the reply, Kees.

I was over-simplifying, I think.

My homework states that my company needs to receive blueprint files from a customer securely. I was thinking using a secure website as an interface for the file transfer. The customer would upload the files to the website and my company would retrieve the files. I was assuming that since it was a company sending me the files, that it would be one IP address because they should upload them from their work, which I would think would have one static IP for all outgoing traffic.

My idea was to only allow the customer's static IP to have access to the website. I was thinking that the firewall rule would block all other IP addresses from accessing it.

Am I going about this in the entirely wrong way? My only experience with this sort of thing is that my (real, current) work receives marketing data from a vendor monthly, and the vendor has set up a website that we use to receive the files.

Then study the user manual ...

of the firewall (software or appliance) of your company to see if it supports blocking by IP-address. I'm rather sure ZoneAlarm Free 9.x (that's what I use at my home PC) doesn't.

Light bulbs you shouldn't buy

There are plenty of dimmable LED light bulbs, but make sure you don't buy the ones that flicker when you dial them down.
