linksys wireless router ftp server

How to find my PC’s public ip when connected via a wireless router through a broadband router to the internet?

I want to find my PC’s public IP, or forward it some way, so I can hit the ftp server I’m running from the internet.
My setup is:
Internet -> Linksys Broadband router -> Linksys wireless router -> my PC
I know the WAN IP of my Broadband router but my PC’s private IP is being assigned by the wireless router which is being assigned an IP by the BB router. So how do I get to hit the ftp server running on my port 33 to be accessed from the internet?
thanks

You would need to forward the ftp port from the broadband router to the wireless router (how you do that depends on the broadband router), and then forward it against from the wireless router to the PC (how you do that depends on the wireless router).
