Personal/Client Firewalls
The AT&T Global Network Client program uses IP to communicate with other computers on the network
just like other network programs (such as web browsers and e-mail programs). Third-party personal
firewalls can prohibit certain types of network communication. Running multiple firewalls on users’ PCs
can cause difficulties and is not supported by AT&T.
Some firewalls must be configured to allow the AT&T Global Network Client to communicate with the
network in order for client features to function properly. The table below lists the required changes.
More information about the features is found in the list below the table.
