Table 4-3: Default access permissions for incoming and outgoing traffic types
To change a port’s access permission:
1. Select Firewall|Main.
2. In either the Internet Zone Security or the Trusted Zone Security area, click
Custom.
The Custom Firewall Settings dialog appears.
3. Scroll to locate High and Medium security settings.
4. To block or to allow a specific port or protocol, click the check box beside it.
Be aware that when you select a traffic type in the High security settings list, you
are choosing to ALLOW that traffic type to enter your computer under High
security, thus decreasing the protection of the High security level. Conversely,
when you select a traffic type in the Medium security settings list, you are
choosing to BLOCK that traffic type under Medium security, thus increasing the
protection of the Med security level.
5. Click Apply, then click OK.
Adding custom ports
You can allow communication through additional ports at High security, or block
additional ports at Medium security by specifying individual port numbers or port
ranges.
To specify additional ports:
1. Select Firewall|Main.
