Hi,
Yes we can do that and the process used is referred to as "DNS Doctoring".
Here is how we can do it:
Create a static translation for the web server like this:
static(inside,outside) 206.29.137.58 dns
Here dns is a keyword.
Also, on the outside interface we should have an access-list which should allow access to this ip:
access-list 101 permit ip any host 206.29.137.58
access-group 101 in interface outside
I hope it helps.
Thanks
Ashu
