Firewall
Dlink DRO-210i User Guide 38
Note: When an active policy is disabled or deleted, another enabled policy will
become active. In this case, currently ongoing sessions will no longer function if they
are not permitted by the new active policy.
The traffic flowing from UnTrusted to Trusted network is the Inbound traffic. By default,
all network traffic going from UnTrusted network to Trusted network are blocked. Port
Filter rules can be added to allow specific traffic.
Select Firewall →
→→
→ Policy to get to the Policy Table, and click In button to configure
Inbound Policies.
Inbound Policies
Port Filter
Enabled Select Enable to activate Inbound Port Filter. Port Filter is used
to allow network packets coming from the untrusted domain.
Configured inbound port filters will not take effect if this field
is disabled.
Deny all services to be
accessed except "Permitted
Service"
Click on “Permitted Service” to configure the port filter rules.
Note: Some old eMail and FTP Servers use IDENT protocol to automatically identify
the users connecting to them. By default, the firewall in the router will block the
incoming I DENT protocol at an UnTrusted port. This will cause eMail and FTP
access to these servers to slow down. To avoid this problem, Port 113 should be
opened explicitly in inbound firewall policy at the router.
Permitted Services
Click on the link “Permitted Services” to get to Permitted Services configuration page.
This page allows administrator to configure the application to be allowed from UnTrusted
network to the Trusted network.
