NIS 2010 & UDP/TCP (World of Warcraft)

I am trying to patch World of Warcraft and have recently installed trial of NIS 2010.

I keep getting the error 'your computer appears to be behind a firwall' and told to enable UDP and TCP ports:

 

  • 80
  • 1119
  • 1120
  • 3724
  • 4000
  • 6112
  • 6113
  • 6114
  • and 6881-6999.

to enable the download to continue, but for the life of me cannot figure out how on this version.

 

Can anyone give me a hand with this?
