Releases Feature Information
TCP state bypass 8.2(1) This feature was introduced. The following command was
introduced: set connection advanced-options
tcp-state-bypass.
Connection timeout for all protocols 8.2(2) The idle timeout was changed to apply to all protocols, not
just TCP.
The following command was modified: set connection
timeout
Timeout for connections using a backup static
route
8.2(5)/8.4(2) When multiple static routes exist to a network with different
metrics, the ASA uses the one with the best metric at the
time of connection creation. If a better route becomes
available, then this timeout lets connections be closed so a
connection can be reestablished to use the better route. The
default is 0 (the connection never times out). To take
advantage of this feature, change the timeout to a new value.
We modified the following command: timeout
floating-conn.
Configurable timeout for PAT xlate 8.4(3) When a PAT xlate times out (by default after 30 seconds),
and the ASA reuses the port for a new translation, some
upstream routers might reject the new connection because
the previous connection might still be open on the upstream
device. The PAT xlate timeout is now configurable, to a
value between 30 seconds and 5 minutes.
We introduced the following command: timeout pat-xlate.
This feature is not available in 8.5(1) or 8.6(1).
