I am using cisco 2821 router. Initially other person has configured that router. But I just want to change one thing in that router. I need to change this below line.

ip nat inside source static tcp 172.*.*.1 80 117.218.*.* 80 extendable

I need to change this line to

ip nat inside source static tcp 172.*.*.2 80 117.218.*.* 80 extendable

Just changing the ip address. I know some commands like,

RouterR1# show running-config
RouterR1# config t

But I don't know how exactly change this particular line in that Router. How can I change this?

Simply use the "no" form of the command to remove the first statement, then add the second one. Like this:

config t
no ip nat inside source static tcp 172.*.*.1 80 117.218.*.* 80 extendable
ip nat inside source static tcp 172.*.*.2 80 117.218.*.* 80 extendable
