Note : By default, HTTPS and SSH do not provide strong client authentication since only a password
is required to access the system. Therefore, these protocols are not considered secure enough for
use over external interfaces. They can be considered secure if you employ a remote authentication
server that provides two-factor authentication. In that case, you may opt to modify the firewall rule
and allow HTTPS and SSH on external interfaces.
The default firewall rules should be sufficient for most users. However, you may create a
set of custom rules if you desire more granular permissions for the protocols you are
accessing.
Additional notes on the D400 firewall:
• In a redundant setup, the same firewall rules above apply to both the active and
standby device.
• When the firewall is active, you cannot perform IP routing between an external and
internal interface. The only way to pass through the firewall is by using a secure SSL/
TLS connection or the proxy.
Configure the settings of the firewall through the
