port forwarding

[Livzz]

i'm sorry if this is a common topic, but nothing i found in the search really helped me...

I'm trying to open a specific port to my computer, but i'm having trouble...

heres my understanding:

my computer is on a wireless home network, pretty much like this:
computer >> router >> modem >> internet

I want to be able to receive incoming connections through a specific port, but i'm having trouble. The router is set up to forward incoming connections through the port to my computer (IP: 192.168.0.6). but according to http://www.canyouseeme.org/ the connection doesnt work.

the port checking website, as expected, tries to connect to the port through the modem's IP address... so could the reason for it failing be something to do with the modem? the only setting i can change on the modem is to enable or disable NAT (i have no internet what-so-ever if it is disabled...)

I've even tried disabling every firewall i can think of...

... help?

What kind our router do you have?

What port are you trying to open?

Does the program need TCP or UDP? Which did you enable for that port? If in doubt enable both.

What program needs that port?

Was that program running when you tested it? IMHO, if no program is availble at the time to connect on that port, i believe that the connection would fail.

Are you SURE that you got the right port?

Are you SURE that you used the right internal IP address?

And you always need NAT. Is there more options for NAT? For instance: can you change how strick it is?

NOTE: In general we need more specifics, we can't diagnose based on: "it didn't work". I'm good, but I'm not that good ;-D

haha fair enough - i'll try be more specific

My computer is running 64bit vista, using a NETGEAR WG311T wireless adapter to connect to a NETGEAR WGT624 router

I tried to connect while running a small webserver on the port in question (i dont wish to specify the port number for security reasons - and isnt it arbitrary anyway?)

I enabled it for both tcp and udp

yep - 100% positive i got the port number and internal IP address right.

nup - only options for NAT are enable/disable.



new development though - I'm now using uPNP within the program i wish to use, and my router is acknowledging the program's request and is automatically forwarding the requested port to my computer no matter what my ip address is.

I don't like uPNP personally....

You can only forward ports to static machines in the router. For example, my bit torrent client is forwarded from the router to the specific machine I use it on. This allows for faster and better connections. I go into my router, select the machine I want to give a static IP to, and typically they are listed by MAC address. Assign a static IP to that machine and then forward all ports to that machine.

then your task should work.

They pretty much have anything about port forwarding.

You need to set up a static IP on the computer you need it on, you need a static IP before you can forward any ports. If its similar to my router, the place you forward the ports, you'll enter the static IP you made in the same location.

Go to that website, and follow the instructions on how to set up a static IP.
