Cisco C3945 support the NAT ALG function?

[haininghuang3185]

I would like to know Cisco C3945 routers can support NAT ALG function? Is this feature enabled by default? How to check whether this function is enabled?

[pieterh]

the obvious command to check if it is enabled would be
     show running-config view full | include ALG

the page to check if current hardware + software version support this would be
Cisco Feature Navigator
