Re: Upgrading Free to Pro
Security risk is zero.
The ports opened are still not internet ports, just ports of your LAN. So this is safe. Your are still stealthed from the internet by the ZA.
The ICS is only set up either for the specific LAN IP(s) or the entire LAN and not the internet itself. Thus the internet ports are still very secure. [This applies to all software firewalls, even the windows firewall, except the windows firewall has no outbound application control].
I assume you have a router with SPI/NAT or a NAT type of modem in front of the PC? This alone blocks all unwanted inbound connections. Thus keeping your PC or LAN safe.
