> How do I change the dynamic time out ?

For example:

ip nat translation timeout 60
ip nat translation tcp-timeout 60
ip nat translation udp-timeout 30
ip nat translation finrst-timeout 10
ip nat translation syn-timeout 10
ip nat translation dns-timeout 30
ip nat translation icmp-timeout 10

Values to be discussed...

Iff you use reflexive ACL, 
you should set their timeouts nearby, I think greater.
