Figure 55 High Level Firewall Protection Screen

If you select high level of protection, you will need to configure additional parameters for the firewall.

■Fragmentation half-open wait - Configures the number of seconds that a packet state structure remains active. When the timeout value expires, the Router drops the un-assembled packet, freeing that structure for use by another packet.

■TCP SYN wait - Defines how long the software will wait for a TCP session to synchronize before dropping the session.

■TCP FIN wait - Specifies how long a TCP session will be maintained after the firewall detects a FIN packet.

■TCP connection idle timeout - The length of time for which a TCP session will be managed if there is no activity.

■UDP session idle timeout - The length of time for which a UDP session will be managed if there is no activity.

■H.323 data channel idle timeout - The length of time for which an H.323 session will be managed if there is no activity.
