HELP!! Can not connect web server after DNS doctoring..

Dear All,

I have ASA 5510 version 8.2(5).

Network topology is following:

localnet  -

Servers -

Outside network.

www server has an address and static NAT to public address

problem - client can not connect to server from localnet network.

I Use this document:

Perform DNS Doctoring with the static Command and Three NAT Interfaces Configuration Example

after configuring when I try to ping web server from asa

write: ping it returns echo reply correct, from private address... but I can not receive echo answer, when I try  to ping server from client pc (local network)...

here is my config:

hostname gw1


enable password 8Ry2YjIyt7RRXU24 encrypted

passwd 0p/CqCPqhGpaiy.f encrypted
