Hi S.H,
In the Program Permissions list, typically McAfee Personal Firewall will prompt you to accept or refuse an application's attempt to access the Internet. When you make your selection, a rule is created by the Firewall to enforce your choice.
If an application does not have a rule allowing it to access the Internet, your Personal Firewall will block the application to protect your computer. You can manually add applications to the Program Permissions list .
Ø Granting Full Access will allow the application to both send and receive data.
Ø Granting Outbound-Only Access prevents the application from receiving data.
Ø Block Access prevents the application from sending or receiving data.
Ø Delete Program Permission removes the application from the list.
Since web accelerator is a proxy server based application , it could be given Outbound only access under the firewall permission list
Hope this information gives you a better understanding about the firewall concepts.Please feel free if you have any more queries
