I currently have comast, and nothing is blocked.. Port 80,21,25,443 etc its' awesome with a normal residential account. In addition, my IP address on my dynamic service changes maybe once a year, it's like having a static IP. I know Verizon changes your IP frequently, and I know port 80 inbound is blocked for sure. What about other ports? Sure I can change my FTP to run on port 20, but that's' a pain for dumb users. I don't use it that much but it's nice to your own FTP box. Sure, you can sign up with one of those port redirection services but that gets to be a pain. WIth fios there is no getting around using one of the dynamic DNS services for sure, but I can live with that. The port blocking is the real issue for me. Sure, I can sign up for a business account but that's over $100 a month. I'd love to get fios quantum service and with my TV service pay 1/2 what I do with comcast and double my speed, but then the port blocking is an issue for me. Sure would be nice if they offered a service for people like me that use very very little bandwidth without have to get a business account. Would appreciate any replies from other users ... Get as technical as wish.. 20 years IT experience.
