Packet8 does not request inbound connections, so no configuration
to accommodate these is necessary.
Firewall Settings for ViaTalk
ViaTalk seems to use a broad mix of ports for its VoIP services, all of which require inbound
connections or port-forwarding to the computer running the ViaTalk client. In
addition to normal web TCP port 80 outbound connections, ViaTalk requires inbound
UDP configuration for ports 69, 5060, 5061, and 10000 to 20000.
Resolving Firewall Issues
As you encounter potential firewall issues with any application, you can rest assured
that someone else has encountered the same or similar problem with the application
or the firewall, and can explain a fix or, worse, indicate unquestionably that your
particular mix of firewall and application will not work together. You should investigate
applications or products you are considering purchasing by searching out reviews
and support issues at sites such as CNET.com, and of course searching Ask.
com, Google.com, and other reference sites.
One tricky item to note for any application that requires inbound port access
through your firewall: the inbound port access in most hardware firewalls allows
that inbound connection to one and only one computer/IP address. Therefore, with
typical consumer firewalls, allowing more than one computer access to and use of
such applications is very difficult, if not impossible. You are better off choosing applications
that can function with and rely on only outbound connections.
