access-list outside_access_in extended deny ip any any
access-list outside_access_in extended permit tcp host 92.67.197.100 host 172.16.1.10 object-group Public_Web-TCP
[/b]

these need to change. you need to completely omit the deny ip any any ACE and you need to change the other ACE to read something like:

access-list outside_access_in extended permit tcp any host 92.67.197.100 object-group Public_Web-TCP

for your second problem, you need to issue another static:

static (dmz,inside) 172.16.1.0 172.16.1.0 netmask 255.255.255.0

Thanks i have changed it to :

access-list outside_access_in extended permit icmp any any
access-list outside_access_in extended permit tcp any host 92.67.197.100 object-group Public_Web-TCP

global (outside) 1 interface

access-group outside_access_in in interface outside
route outside 0.0.0.0 0.0.0.0 92.67.197.97 1

I can access my web server from the net
But not yet form the inside :-(

let's try this:
1) remove these lines:

static (inside,dmz) 192.168.1.0 192.168.1.0 netmask 255.255.255.0
static (dmz,inside) 172.16.1.0 172.16.1.0 netmask 255.255.255.0

2) add these lines:

access-list nonat_inside extended permit ip 192.168.1.0 255.255.255.0 172.16.1.0 255.255.255.0
access-list nonat_dmz extended permit ip 172.16.1.0 255.255.255.0 192.168.1.0 255.255.255.0

nat (inside) 0 access-list nonat_inside
nat (dmz) 0 access-list nonat_dmz

3) issue this command:

no nat-control

i have deleted

static (inside,dmz) 192.168.1.0 192.168.1.0 netmask 255.255.255.0
static (dmz,inside) 172.16.1.0 172.16.1.0 netmask 255.255.255.0

and add

access-list nonat_inside extended permit ip 192.168.1.0 255.255.255.0 172.16.1.0 255.255.255.0
access-list nonat_dmz extended permit ip 172.16.1.0 255.255.255.0 192.168.1.0 255.255.255.0

nat (inside) 0 access-list nonat_inside
nat (dmz) 0 access-list nonat_dmz

still the same
i can ping 172.16.1.10 and 172.16.1.11
but when i open my web browser and i try to open my webpage
i can't access it :-(

 

[unclerico]

Ok, try accessing the web server. Then issue sh logg asdm. The logs will give a better indication of what is going on.

[unclerico]

are you by chance trying to connect via the public FQDN as opposed to the private name?? what i mean by that is if you can access it outside by

http://www.fubar.com,

are you trying to access it from the inside by

http://www.fubar.com

also?

[Sikkie]

yes im trying to access

http://www.fubar.com

from the inside.

 

[unclerico]

Ahhh, that is why. You need to configure dns doctoring for it to work properly. I'm Typing on an iPhone right now so I'm not going to try and write the entire statement, but google cisco pix dns rewrite and you'll find out how to get it done.
