TP-Link Port Forwarding

[Xiphan]

Hey everyone,

I recently bought a TP-Link TL-WDR4900 and so far it has been an amazing router until I tried manually forwarding a port. For some strange reason when I try test the port using an online port checker it remains closed.

Has anyone had any experience with this? UPnP works like a charm but I am trying to setup the web interface of my torrent client which doesn't request the port to be opened via UPnP.

Is there an actual machine replying to the port forward?

I would use TCPDump/Wireshark to diagnose where the fault is. i.e. the router or the machine.
Also have you tested that you can access your torrent client web interface from another machine on your local network?

For the life of me the other day when I tried this it wasn't working and yet today I was greeted with my login prompt and lo and behold it is now working!

I'm accessing the above from my PC at work. As for how I am getting my IP without paying for a static IP or using a Dynamic DNS service I setup a command in Ubuntu to run every hour which saves my public IP to a txt file in my Dropbox. A simple yet highly effective solution which requires very little admin when my IP address changes.

The command in question if you have a nix box is:

curl ifconfig.me

And to make it save to a text file:

curl ifconfig.me > ip.txt

Then to make it run every hour you just add the command as an entry in chrontab or use the schedule tool to add the entry for you.

Nice! Yup, the crontab is pretty nifty for script scheduling...

Doesn't the router offer no-ip.com as DDNS? Or a free tp-link one? That would be a simple, effective solution rather than having a PC run all the time
