Okay, so I'm working on a little Networking with Python using the 7.2.3 example on python.docs.

To test it I switched it to:

server
host - "compaq"
port - 2222

client
host - 192.168.0.xxx
port - 2222

And it worked, because for host I put the network IP.

But when I try to replace the network IP with my internet IP (so people from outside my network can access it), the client times out. I've tried replacing the server's hostname with the internet IP, tried changing ports. I've tried switching client/server with friends. Made sure no firewall is up.

Can someone give me a working example for two computers outside of the same network?

you sure you dont have to do any port fowarding in your router? (that is if you have a router)

Sane · Nov 20th, 2005, 8:43 PM

Yes, I have a router. But as I said, I've tried switching client/server sides with my friends.

Ok. Does your friend have a router then?

Why does a router matter anyways? Like I didn't think playing an online game was connected any differently with a router then without. Shouldn't that apply to the socket module as well. If not, then what's the solution?

If you're behind a NAT, then you can connect to computers through your router, but they cannot connect back to you. The typical way to solve this problem is port forwarding; you tell your router to forward all incoming connections on the port X to your localmachine.

For instance, my router forwards port 22 to my Linux-based NSLU2.

But if I'm trying to sell this product, I don't want to make all my customers have to forward a port if they have a router.

Well, anyone who's hosting the game will have to forward a port... how many people are gonna be doing that? And if they are, you'd hope they'd know enough to do that already.

Nah, it's for a Remote PC Accessing program. So the program is for someone who wants to be able to access their computer from a distant location without having to worry about uploading crap, or paying for a domain name. This need applies to a lot of people, including those who had no clue port forwarding existed (IE, me).

And I'm also using the same framework for an FTP emulator under similar circumstances.
