It depends on what SSL is being used for (HTTP, as in secure web pages; FTP; Telnet; etc.). Below is a non-exhaustive list of various port numbers used for protocols with SSL implemented: * HTTP: Port 443 * FTP (Data): Port 989 * FTP (Control): Port 990 * Telnet: Port 992 * IRC: Port 994 * pop3: Port 995 I hope this was the information you were looking for.
