Unblock UDP port

I am trying to set up a wireless printer (HP), and have gotten the error message "If you are using firewall software, verify UDP port is uhnblocked from your printer at".  I tried to follow directions that I saw in another post where someone was trying to unblock a port, but I don't know what number port the UDP port is.  I would appreciate any help someone could give me.

You could also do something similar via Network Security Map!


Click Network Security Map(Main Page Norton User Interface) -> Ok -> Click +(Left of Window, just below Total in Network) ->

Enter Device Name and the IP Address and click Add Device.



Hope this is helpful,

Re: Unblock UDP port

Thanks for both suggestions...I decided to try Doug's since it seemed easier, and so far things are working fine.  If for some reason things don't work down the road I'll be back.  Otherwise...thanks a bunch!
