i have been trying to log onto my ftp server from college for some time now with no success. my college has a very tight firewall/proxy. i have a firewall (router) at home (where the ftp server is running). i have opened the right ports to alow me to conect to the server from other places. i just can’t seem to get on from college. when i try to log on to my cerberus server with smartftp i get this message.
“HTTP/1.1 502 Proxy Error ( The specified Secure Sockets Layer (SSL) port is not allowed. ISA Server is not configured to allow SSL requests from this port. Most Web browsers use port 443 for SSL requests. )”
i am not familiar with what ssl is. i know that it stands for secure socket layer though. i don’t need a secure connection.
in smartftp i have set the proxy settings to “HTTP Proxy – Connection Tunnel.” thanks for the help, aaron
howdy, I might have the info for the reason of the problem. You see, i too was having that exact same problem, so i went to the Administrator (me and him are good buds) and asked him why it wouldnt work, he said that he disabled FTP support through their proxy (which when enabled, would emulate a FTP client and send it to the computer in HTML format). He disabled it for some reason he would tell me, but im not sure it would have to do with the type of proxy.
Try to change the port you are using for the server to a port that is normally used for HTTP browsing (Port 80 is the usual) and see if that works. If it works then they have just disabled port 21 (which is the normal FTP port). If still no luck, then i hope you are good friends with the administrator, because you will probably have to talk with him.
