I strongly belive its not a Gateway issue...because they are accessing the NATed IP through WAN link....more over from the same machine user can access the another NATed IP which are in same subnet as I mentioned my earlier post.

Sorry Dove but i don't understand your post.

because they are accessing the NATed IP through WAN link...


What do you mean access the NATed IP through WAN link ?

the same machine user can access another NATed IP which are in the same subnet


Another NATed address in the same subnet ?

--

So, one static NAT translation to another server in the same subnet as the one that doesn't work is working ok ?

Can you provide a drawing of your environment with the pasted config (without passwords and mask the ip addresses), i am guessing the problem still exists ?

hi hope this would help you out.

access-list 110 extended permit icmp any any echo-reply
access-list 110 extended permit icmp any any time-exceeded
access-list 110 extended permit icmp any any unreachable

global (outside) 10 interface
nat (inside) 10 <IP-RANGE> <SUBNETMASK>
access-group 110 in interface outside

this will give you a basic natting from the inside interface to outside. this is a full nat setup so every traffic passed through the inside interface gets translated. (tcp,udp,icmp, etc) will get through. if you are concern about icmp on the outside interface you can always do the following.

icmp deny any outside

goodluck.

At this point I agree with Smurf, a diagram with some configuration will greatly help us get an idea how your setup is and make the necessary recommendations.
