I have been trying to set up an ftp and it seemed to be going very smoothly. After it was set up I discovered no one could connect. I went to www.grc.com after reading some posts here and discovered that my ISP has me in stealth mode, so while my ftp is up and running, no one can get connected. I am wondering if I can change this short of contacting the ISP, and if not what to do when I contact my ISP.
I didn't find the right solution from the Internet.
