Hi people,

I'm kind of new to networking, I googled and searched this site, but could not find a good answer to my doubts about networks:

1 - I'm behind a router, and I had the router admin configure it to pass 3 ports directy to me, so others could connect to my PC using those ports. How can I know that it worked??? How can I test if those ports would trully receive connections??

2 - I seam only to be able to see my IP from within my local network. I mean, when I try to find out my IP I do not see a true IP, I get something in the range of reserved IPs for local nets. When another person is connection to my machine it should connect not to this IP, but to the IP with witch people all over the world see my internal network. How can I find this IP???

Thanks,

Felipe

If you are behind a router that performs NAT, you SHOULD be getting a "local" IP address. That is perfectly normal.

If you want to test it, you'll need to try to access those ports from OUTSIDE the routed network.

But, how can I find the IP with witch people outside my network see me???

Well, the router has that information. Also, there are webpages out there that can tell you that.

Thanks!

I'm gonna try using sshd to test the port...

Good like. Remember it must be from outside the router. (This is for complex technical reasons regarding tcp/ip)

Oooh, good link heema. I have to remember that one, obvious as it is.
