Port Forwarding Problems..Need Help:)

ok I know alot about hardware, but next to nothing about routers that stuff, etc.

We have a main computer down stairs connected to our router. My laptop is in my room upstairs connecting wirelessly as well as another dekstop upstairs.

Now when I go ipconfig/all in command i get.

IP: 192.168.0.100
and all of that other junk.

but i just recently learned that my external ip adress is 64.231.207.190. What is this?

Every time I test to see if the port is forwarded it says its not, and I have followed this online guide very closely and Have tried over 5 times and I am getting pretty pisssed of. I have went into the router using my static Ip address and opened it in the router for the program with the port im using.

Is it different for laptops? I am sorry im asking so many questions, many of them stupid I am sure? If you can help me figure this out I will rep you every time I can and praise you like a god!

TIA!

 

It shouldn't be different. You should specify which router you're using.

If you are doing a static port forwarding, you map the "public" port from the router to a private (and usually static/fixed) IP and port. For example, map public 5881 to private 192.168.1.100 port 5881. Or even public 6881 to private 192.168.1.100 port 5881. In both cases, you would still run the program on port 5881 and it would listen externally on the public port.

Also make sure that the laptop's firewall is also not doing any sort of blocking. If you use the WindowsXP SP2 firewall, you have to let that port through or have that application unblocked.

I don't suggest using UPnP port mapping. It tends to cause more problems than good.

 

ok it just doesnt want to seem to work for me....I have neevr been bale to get this to work....

 

Rest your computer back to their original config, DHCP. Your router has the public IP, and all pc connected to the router should be private. The router does the nat and sends what each pc request to their private IP.

Now back to port forwarding. What you need to do in the router is add the rule that points the port you want to forward to the private IP of your pc. A router will issue the same IP to same pc as long as the routers is not reset or powered off.

Now some ISP block specific ports to prevent Web Servers, BT ....

Once you do a port forward you can use this site to see if its open, http://www.hashemian.com/tools/port-scanner.php

 

Should just be able to go into your routers config page (usually 192.168.0.1) then go to advance setup and then when you get to port forwarding and DMZ hosting turn them on and put your ip address in them.

 

thanks guys will try and rep you later...ive given too much apparently :\

 

So it worked apprently? Did the printer info work I gave you earlier?

P.S. Lets make babies blue.

 

im trying now...we will see

 

didnt work.....d#Am im getting mad

 

Call your ISP, some block it on purpose and you have to call and ask them to unblock it.

 

o, they will just unblock it? sick....ill try tomorrow then.

 

Depends on who you have, and if they can't figure it out they usually will send you new hardware

 

What are you trying to do? I still don't know what you are trying to accomplish. About you question, 64.231.207.190 is a public ip address. That is the ip address that you use to communicate on WAN, which is internet in this case. 192.268.x.x is a private ip address, which is a class C in this case. Your router is using NAT (Network Address Translation). Cisco calls PAT (Port Address Translation). Anyway, if you try to do port forwarding, you have to map from public ip address to private ip address. This will enable you to do something like FTP, Remote Desktop, Web server from outside your network such as public internet.

If you want to communicate between your LAN, which is in your house in this case, you don't do any port forwarding on your router. I will assume that you are in workgroup, so you have to take care of your computers firwall, which is software in this case. Take a look at your Windows XP firewall if you want to do file sharing or share printer.

This is just a general pointer I can tell you. Am I right Amped24? Do I sound like CCIE to you? I am still waiting for you to come and audit my network.

 

You sound more like a CITRIX then a CCIE or a MServer+, maybe a CCDP. Maybe you are a CCIE who knows I'll be one within three months

I beleive he wants DMZ hosting on and not Port Forwarding. I think he has the two mistaken as many do.

 

yes i would like DMZ(De militarized zone)(i know things too )

Do i set that to my private IP then? or the public one?

 

Well, whatever you think I am not, I may be all of them and much more. If he wants DMZ, he still have to do port forwarding anyway. He can't avoid that. I personally don't like CITRIX, I am more like SMS person. Whatever you said, I will take it as a complement.

 

should be private if i remember right. Youll have to restart your router. Save and restart in the menu.
