Skype and firewalls
What is a firewall?
A firewall is a program that keeps your computer safe from hackers and malicious software.
Why do some firewalls block Skype?
Some firewalls may not know about Skype yet and mistakenly block Skype from accessing your system – an error message Skype error #1102 will be displayed. Skype should work with any firewall. If you are having problems connecting to Skype, refer to the firewall guides on this page for help.
