Unneeded virtual servers (port forwards)

I have a D-Link router with a limited number of virtual servers, so I want to delete some of the default ones, but I'm not sure if any of them are important. Here's a list:

      Virtual Server FTP      0.0.0.0      TCP 21/21      always      editdelete
      Virtual Server HTTP      0.0.0.0      TCP 80/80      always      editdelete
      Virtual Server HTTPS      0.0.0.0      TCP 443/443      always      editdelete
      Virtual Server DNS      0.0.0.0      UDP 53/53      always      editdelete
      Virtual Server SMTP      0.0.0.0      TCP 25/25      always      editdelete
      Virtual Server POP3      0.0.0.0      TCP 110/110      always      editdelete
      Virtual Server Telnet      0.0.0.0      TCP 23/23      always      editdelete
      IPSec      0.0.0.0      UDP 500/500      always      editdelete
      PPTP      0.0.0.0      TCP 1723/1723      always      editdelete
      NetMeeting      0.0.0.0      TCP 1720/1720      always      editdelete
      DCS-1000      0.0.0.0      TCP 80/80      always      editdelete
      DCS-2000      0.0.0.0      TCP 80/80      always      editdelete
      i2eye      0.0.0.0      TCP 1720/1720      always

Which ones can I delete?

Thanks

The following are duplicates:

i2eye     0.0.0.0     TCP 1720/1720     always
DCS-1000     0.0.0.0     TCP 80/80     always     editdelete
DCS-2000     0.0.0.0     TCP 80/80     always     editdelete

And can probably be removed as they are not specifying a virtual server, just opening those ports in general by the looks of it.
