Figure 65 High Level Firewall Protection Screen Firewall 83 If you select high level of protection, you would have an option 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.

Figure 65
High Level Firewall Protection Screen
If you select high level of protection, you would have an option 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.
