hey i have a server on comcast@home account. just small web and ftp which is locked down so only i or someone i know can get into it. now if i connect to the internet using verizon it will not work....the right way. ex. i run remote desktop it will connect but show nothing but a black screen then timeout. same with the ftp, it will connect and ask for password but never show whats on my ftp. anyother brand x isp works fine but not verizon any ideas?
