e-Safe Help - Getting Started - Running e-Safe with firewalls
If you are running
a personal firewall on your computer, you will have to allow
e-Safe to transfer data in both directions to work properly.
If you wish to limit access to a range of IP addresses, set
your firewall to allow two-way access through port 21 to IP
addresses 82.110.111.0 through to 82.110.111.255.
