Symantec endpoint manager download defs through HTTPS?

Hi All,

I noticed that SEPM uses port 21 and 80 to download its virus definitions. Is there no way to configure SEPM to use port 443 to obtain updates? Are there any links other than the ones listed below?

• http://liveupdate.symantecliveupdate.com (port 80)
• http://liveupdate.symantec.com  (port 80)
• ftp://update.symantec.com  (port 21)

Thanks
