Where can't you browse your web server from? I tested browsing it from the internet, it works just fine.

If you are trying to browse from your inside network, you would need to configure the following static statement:

static (inside,dmz) 192.168.1.0 192.168.1.0 netmask 255.255.255.0

Then issue "clear xlate" to clear the existing translation.

Lastly, from the inside, you would need to browse to the private ip address of the server as follows:

http://172.16.1.10

Hope that helps.

Marcel,

The problem is at your home then....

Can you browse other pages correctly from the Internet?

If you are from the internal network, the dns resolution for"www.sikkie.nl" probably resolves to the public ip address instead of the private ip address.

You can try browsing the website via its private ip address as suggested earlier.

So instead of "http://www.sikkie.nl", try "http://172.16.1.10" when you are from the internal network.

If the dns entry for "www.sikkie.nl" is hosted on the Internet dns server, then you can configure dns doctoring as follows:

Change the following static statement from:

static (dmz,outside) 92.67.197.100 172.16.1.10 netmask 255.255.255.255

TO:

static (dmz,outside) 92.67.197.100 172.16.1.10 netmask 255.255.255.255 dns

DNS doctoring will only work if the dns entry for www.sikkie.nl is hosted on the outside.

To test, you would need to flush the dns entry on your PC, so it triggers dns request through the ASA, and the reply will change the dns entry for www.sikkie.nl from 92.67.197.100 to 172.16.1.10 so you can access the website internally using its private ip address.

Hope that helps.
