FIREWALL PROTECTION SETTINGS
Firewall is a built-in network security feature in the iSavi
™
to monitor and control the incoming and outgoing
network traffic by analysing the data packets based on predetermined security rules. It is highly secure and
reliable that uses packet inspections to prevent hacker’s attack.
With Firewall feature, you can:
• Block the unwanted traffic from the Internet network to your terminal.
• Block access from your terminal to Internet network locations.
• Filter the host names.
• Control the internet network access by using the keywords on the web addresses.
You can define up to 10 rules to allow or reject incoming IP packets from the public network. The filtering
rules are based on the protocols, IP addresses (source/destination) and port numbers (source/destination).
Firewall function is disabled by default. Navigate to the firewall setup page to enable it.
Scenario: Allow only internet browsing but block all other traffics on any connected devices
To block all other traffics on any PCs but only allow Internet Browsing, we have to reject all incoming
packets and allow only two ports under both incoming and outgoing rules.
Port 80: Internet Browsing
Port 53: DNS lookup
