Difference between these two NAT types

[isaaco001]

Dear community,

I have implemented two nat types and am able to achieve the same result. The nat types are static and port forward nat as below: 

nats

nat (inside,outside) source static R1 ASA102

nat (inside,outside) source static static R1 ASA102  service telnet telnet

objects

ASA(config)# sh run object
object service tel
service tcp source eq telnet
object network R1
host 192.168.1.2
object network ASA102
host 101.1.1.102

I am able to telnet to R1 through ASA102 using both nats, so whats the difference here?

Regards,

Isaac

you do not see any difference in terms of operation, But the order process will be changed. look at the below document :
