Communicate through a tunnel (ssh?) 300-1000pts

Okay experts!
1. I'm from Germany and my english is not very good. :o(
2. I am not very good at programming.

What I want to do:
I'd like to exchange data (Text and numbers!) with 1 other PC over the Internet using any protocol.

Problem:
My computer connects as follow to the Internet: WLAN to a router, over a Mac as Gateway and filally over a Server. So others cant ping me or send me anything, except i send a signal and want an answer.
I dont know, what protocol I should use (and how to build the programs)... But it should be a p2p program, so both have the same rights...

I'd be happy, if you could give me a good answer :) <- newbie

Thanks in advance!

Ps: Points variable!! (up to 1000)

I recommend that you download the INDY TCP components. they are open source. There are many peer-to-peer demos
that you can build from.

do a google search for "INDY DELPHI DOWNLOAD"

you'll find it.

Other that that help, your question is far to broad of scope and this is not a "Write a program for me" forum

I agree with KyleyHarris, Indy is the best choice.

source:

demos:
http://www.indyproject.org/indy/demodownloads/I9D6_Demos_24Nov02.zip

you can use TIdMappedTelnet (for server) and TIdTelnet (for client). There is a demo inside...

BTW with Telnet you can execute commands on the remote system shell. For example DIR, COPY, etc. If you want just to send/receive some data, you can use TCP Client / Server...
