Connect a client to another directly?

Specs: Windows XP
Hi everyone, I am simulating a network solution that is basically meant for computers connected to the internet through modems (dial up connections).. My question is if a computer knows the IP and Port of the computer it wishes to retrieve information such as files from, can it connect to that computer directly or it has to pass through the switch( whether it is the building switch or area switch, depending how the ISP wanted it).. please do note that I am talking about rural areas with no broadband technology..

It makes little difference wether you are on broadband or dial up. If you want to retrieve files from a remote computer there has to be software on the remote computer to receive the request and respond to it.

That means some kind of server like and FTP server or VPN server.

The ISP really has little to do with it. They are just a facilitator and take little or no control of what actually passes through their system. I do understand why you think a switch might be involved in it.

I do not have solid background about networks..
so all I have to do is work with the application layer and not the network layer right? by using a software.

For the most part all the end user is concerned with is the application layer. All the intermediate layers are taken care of when the netowrk is built and configured. They are determined by the network hardware and protocols you are using.

If your PC's are all dialup capable then you would directly dial the remote computer. Simple enough, but darn slowwwwwwwww! lol

All you'd need to know is the phone number of the remote computer. Fire up hyperterminal (I'd recommend using TeraTerm instead of hyperterminal) enter the phone number and hit dial.

You will of course need login credentials on the remote computer AND the remote computer would have to be setup to accept incoming calls through it's modem.

Thanks Stuart :)
Curt R! never thought of this :) but I am trying to speed up my connection in here :p not slow it more! The solution I'm working on is basically for Dial up users but later on Im going to upgrade it to be used with broadband technology.

You could create a VPN connection to a computer connected to the internet via dialup, but the resultant speed will be the same as if you dialed directly into the PC as I described above.

When talking about networks and bandwidth, your bandwidth is always controlled by the slowed component. Which is to say, you will always connect at the speed of the slowest connection.

So, in the case of VPN'ing in to a computer that's connected to the internet via dialup, your limited to their connection rate. Which would be the exact same as if you dialed into them directly.
