Re: Open Ports
said by nyrrule27:FTP behind a NAT requires an application-layer proxy service snooping traffic on the NAT itself, and opening ports for each and every data transfer correctly, based on what was requested in the port-21 command(s). It is unlikely that such proxy service on a NAT will ever listen to anything BUT port 21, or is configurable as such.
I setup an ftp server in my house. It works fine when using port 21. as soon as i change it to a different port it doesnt work. is there a list of ports or range of ports that cablevision might be blocking
Do yourself a favor: as you have no bloody clue about the technical details you're up against here - go get yourself a HTTP/HTTPS-capable NAS box (or enable such access, if it supports it), and forward a single arbitrary port to your liking to the HTTP/HTTPS port of the NAS. Problem solved.
