server without port forwarding

What? You either get a router that does support port forwarding or you don't use a router which is not good choice.

A router that performs proxy and reverse proxy could accomplish quite a bit without the need for nat or port forwarding, but this would most likely be a host-based router. If this is a modem/router that supports

1483 bridging, then you could bridge to a device that provides nat and port forwarding.

To do so, you better should have deep knowledge about computing security, or your box will be 0wned soon. Before that, you need knowledge about networking, or you cannot understand.

This is an oxymoron.

Learn. You could start with "TCP/IP" from Craig Hunt. Wikipedia will help, too.

What router model/part number do you have?

Also, if you expose your computer to the public, if you don't completely understand that security threats, you could easily have your machine compromised.

Either

a) buy a better router

or

b) Pay somebody to recommend, install, configure and maintain a better router for you.

I recommend b).

Ok, I've understood that all of you are interested to the security!! But nobody have gave a reply to my question!

I'm interested to be reached from internet but my router hasn't the port forwarding functionality. The answer "buy a better router" doesn't seem to be a really good answer.

Then you don't know a way to do this. That's all.

Wrong, you got the correct answer but you didn't like it.

That is the correct answer. If you are using an IP-address from

192.168.0.0./16, 172.16.0.0./12 or 10.0.0.0/8 (reserverd for private use,) and your router doesn't offer the possibility of port forwarding, then you need another router. Of course you don't need port forwarding if you've got a public IP-address for your PC behind the router. In this case you just need correct routing entries.

From a technical point of view it does not matter at all whether you like the answer or not because the answer is correct.

There are two ways:

- Private IP + port forwarding (+ a router that supports it)

- Public IP (+ routing if behind a router)

If your router hasn't a functionality for static NAT (which is what you're perhaps needing), then "buy another router" maybe is the only way to help you.

Yours, VB.

Your're correct. We don't know how to do something with your router, that your router can't do.

Now, if you can describe for us the particular service that you are trying to expose, there may in fact be a way using a software client on your PC and a server on the Internet to accomplish your goal. Would you care to provide additional detail on what you are trying to accomplish? Or simply continue to demand the impossible?
