Hi there. I have Sygate Personal Firewall Pro and currently I have it set up
to allow the programs I have on my computer that use the net to have access to
all ports and protocols and to be able to act as a server and a client. Is it
worth setting it up so each app has only access to the protocols etc that it
needs?

Thanks

That depends on your computing behavior and whether you are the sole
user of your computer.

Application Control in a PFW solution is bloat junk and if you depend upon
it, it will open the door for you to be burnt eventually.

Hi Michael. If you are running a single computer connected to
internet, I would recommend you set up Sygate the way I have
mine. I have used Sygate for about 4-yrs. My approach is to
"Block Everything I Do Not Use".
In Application Rules, (1)you Allow all applications
that you want to connect to internet. (2)In Applications
Rules--Advanced, you allow each application to only connect
to the remote ports that each one uses. (excluding all other
remote ports) Browser-80, 443; mail client-25,110; mail
client-119 etc... As you set up the App. Rules and if you are in
doubt about what remote port an application needs, look in
the traffic log. It will be listed there. Allow each app. to
act as client. Do not allow any app. to act as server unless
it won't work otherwise.
In Advanced Rules, (1)Allow TCP, UDP and ICMP remote/local
ports incoming/outgoing that you use and block all others.
(2)Block undesirable sites using IP numbers or number blocks.
