I'm currently using the free version of Zone Alarm, v.6.1.737.000 under Windows XP SP2 and Internet Explorer v.6.0.2900.2180.xpsp_sp2_gdr.050301-1519.
I'd like to use Skype to talk with friends and family in other area codes and overseas but have 2 questions.
First, does Skype work with the free version of Zone Alarm or will I have to upgrade to ZA Pro?
In Skype's FAQs, there are instructions for configuring ZA Pro to work with Skype, but not the free version.
Second, the with regard to firewalls, the Skype FAQs state:
"The minimum requirement is that Skype needs unrestricted outgoing TCP access to all destination ports above 1024 or to ports 80 and 443 (the former is better, however). If you don't allow either of those, Skype will not work reliably at all. Voice quality and some other aspects of Skype functionality will be greatly improved if you also open up outgoing UDP traffic to all ports above 1024, and allow UDP replies to come back in.
In the quest for even better voice quality, it is also advisable to open up incoming TCP and/or UDP to the specific port you see in Skype Options. This port is chosen randomly when you install Skype."
Will opening up those outgoing ports create any vulnerability?
For example, could
communicate with its creator thru one of those open outgoing ports?
I assume not, but thought I'd ask first.
Will opening up
incoming TCP and/or UDP to the specific port shown in Skype Options create a vulnerability?
Thanks for your help.
