What kind of server do you want to run?

And for the record, I LOL'd at your picture....

From the diagram, it looks like you are wanting the Linux server to act as a firewall.

Is that accurate or do you not care about restricting traffic/protocols?

Actually yes. I want to control all the internet traffic.

If you are looking to control all traffic, you will want to build up a firewall. Have a look here:

Here is a brief list of already made distributions made just for firewalls, monitoring, etc. You can also check out distrowatch.com.

Can i do this with debian? For the first time please help in just routing. After that please give me some material for doing everything myself. BECAUSE I want to learn.

Sure. Learn the ins and outs of iptables, and how to use forwarding rules. Here is the man page to start:

As far as routing, here is one option:

The internet has many resources. Try searching on google, you will find a lot of topics about what you want to do.

Cheers,

Thanks for help. Believe it will be helpfull.

For what you want to to do, it is simpler than configuring IPTABLES.

All you should need to do is enable IP forwarding.
