Help with port forwarding.

[Saumya Dudeja]

Hi ,
I have a Cat5e ethernet cable coming in my room from the roof which plugs directly into my TP-Link tl-wr740n WiFi Router , I tried port forwarding , but when i go to canyouseeme.org , i get an error saying " I could not see your service on xx.xx.xx.xx on port (xx)
Reason: Connection timed out" .

I have tried disabling windows firewall completely , disabling router firewall , and i still can't get it to work , another thing that I noticed is that , when I plug the Cat5e cable directly into the PC , i get a default gateway , like '10.20.xx.xx' , and the connections to it are refused , can that mean that I am inside my personal network(192.168.x.x) , which is inside another network which can be My ISP (10.20.x.x) , which itself inside is WAN , and so My ISP is only allowing some default ports?Please help me how to successfully forward ports.

Thanks

It sounds like your ethernet in your room is off a router already, that's why you get a 10. which is a private network, like 192.

Go to Google.com and do this without quotes "What is my IP" It will tell you what your public IP is. My guess is you have a switch feeding the ethernet to your room, then you are hooking a router to that. 2 routers. you would need to run IPCONFIG from command prompt to get the gateway information while hooked to the ethernet and use that to log in and configure that router too.

Why are you trying to open ports anyways? issue with a game or program?

I suspect because you say "I have a Cat5e ethernet cable coming in my room from the roof" you are using some form of wireless broadband connection. It is extremely common for ISP like this to use 10.x.x.x addresses because of the shortage of ips.

Pretty much this means you can not port forward because you are likely sharing a IP with many other people. The ISP is running NAT in their network and you would need to do port forwarding on that device which they will not allow.

I suspect your only solution is to call the ISP and see if they offer public ip addresses. If they do they will likely charge extra for it.

Wow I totally missed the from the roof part. That changes things lol.

yep , i just checked it out and they use a wireless receiver to connected to their tower , with 3 more ports for connections , but I can download through torrents , so the torrent ports must be open I guess , so can i use those ports as they are useless when not downloading?

I just got some support from my ISP and they say they'd give me a Static Public IP for $30 , Thanks for your answers and I hate my ISP already.>_<
