Configure the
VT2500
firewall to allow inbound packets without first establishing an outbound session. You
will also need to configure a port forwarding entry on the
Gateway > PORT FORWARDING — config
page or
a DMZ client on the
Gateway > LAN – static leases
page.
High
The safest firewall policy template, that provides the highest security. We
recommend this setting.
Medium
A firewall policy template that provides a common configuration having modest risk.
Low
A firewall policy template that provides minimum security, with a higher risk of intrusions.
Custom
You may need to create your own custom firewall policy
. Do not create a custom policy unless you have
the necessary expertise and the need to do so.
After you edit the field and click
Apply
for some settings, you are required to reboot the
VT2400/VT2500
for
the changes to take effect. Rebooting takes 10 to 15 seconds. After rebooting, you must log in again.
