The Wisdom of Allowing an Open Port

[Jim Pardonek <jpardonek () LUC EDU>]

Good Afternoon,
 
On our hospital campus we have an "open" wlan that requires the usual rudimentary form of authentication (some email 
address and your name) to gain access, similar to a hotel portal.  Some of the medical staff want us to open port 1373 
TCP so that they can access our GroupWise (I know) servers using the regular client application.  Other than the normal 
reasons for keeping everything except 80 and 443 closed, I'm looking to see if anyone would like to weigh in on reasons 
for and against opening this up.
 
Thanks,
 
Jim
