HI.

Can the LAN clients ping the web server?
Are they accessing it by IP address or by FQDN?

Is the web server implementing the "Host Headers" function?

> My lan clients (192.168.0.X) ....
I don't see any reference to subnet 192.168.0.X .
Something is missing here.
Do you have an additional firewall or NAT router?
Do you have an additional internal router?

It seems like a routing issue.
Use the ROUTE PRINT command on the workstation and server.

Bye

HI.

> ... , i make NAT with server 172.16.0.3.

OK I think I got the picture:
The server 172.16.0.3 has 2 NICs: external = 172.16.0.3,
internal = 192.168.0.1.
The LAN SWITCH is connected to 192.168.0.1 .
The server is doing NAT.
The subnet 172.16.0.3 is a DMZ between 2 NAT devices.

Is this correct?

If so, then the problem is not related to the pix.
You should check routing and NAT configuration on the servers.
