Firewall provides bidirectional stateful inspection of incoming and outgoing network
traffic. Firewall rules define what actions to take on individual packets and can
filter packets by IP address and port across all IP-based protocols.
Procedure
- To control internet connections with Firewall, select Enable.
Note
When you enable Firewall, the rule list might be filtered by Enabled status and might appear empty. Remove the filter to view the Firewall rules. - To configure the aggressiveness of the Firewall, set the Security level.
-
High: Blocks all inbound and outbound traffic.
-
Medium: Blocks all inbound traffic, allows all outbound traffic.
-
Low: Allows all inbound and outbound traffic.
-
- To apply a firewall rule to override the security level settings, locate the rule
in the list under Rule management and click to Enable the rule.Firewall rules act as exceptions to the Security level to allow or block specified connections. Rules apply in order of priority from 4 - Highest to 0 - Lowest and actions always override the security level settings. Trend Micro provides preset firewall rules for typical security configurations. You can also create your own firewall rules in Policy Resources.
- To specify a list of trusted programs allowed to bypass the firewall, select a program
list for Allowed programs.
Note
Firewall Allowed programs list only supports Windows agents.You can create and manage program lists in Policy Resources.
