How do I open my port on my router for a netgear wgt624 :( :(

There have been several versions of this device as indicated on the sticker on the device. The Manual for v1 covers port forwarding in chapter 6. If you have a later version, visit the support section at Netgear and download the manual appropriate for your device version.

You can start with the holy site of port forwarding: PortForward.com - Free Help Setting up Your Router or Firewall

And here: Port Forwarding for the Netgear WGT624
