Description (partial)


Timeout value not synced between SNAT active and standby routers for tcp syn packets.  After SNAT failover, those dynamic nat entries will use the tcp timeout value configured on the router, which will take much longer to expire.


NAT dynamic entries are created for short-lived tcp packets in the nat translation table and there is SNAT failover at this time.
