Yeah thatz right..
HSRP/VRRP will satisfy the need.
But I just wanted to check whatz wrong when I use simple dynamic
natting..what goes wrong ?
I tried it with static natting it works..
Wanna make it work with dynamic natting :)
Below the config for static natting :
Router#sh run
Building configuration...
Current configuration : 1519 bytes

end
Router#
This is perfectly fine working config..

Can you run HSRP/VRRP? You can still do your static
route behind it to satisfy your constraint.
