Hi Nuno,

Nothing much just a couple of commands:

Lets say you have a free public ip for your dmz server 196.35.41.82 and the real ip of the server is 192.168.0.20

Then you would need a static:

static (dmz,outside) 196.35.41.82 192.168.0.20

Also an access-list to allow access to the server:

access-list outside_access_in extended permit tcp any host 196.35.41.82

access-group outside_access_in in interface outside

Let me know if you have any questions.

Thanks,

Varun

Hi,

1) first create a static PAT :

static(dmz,outside) tcp interface 80 x.x.x.x 80 where x.x.x.x is your web server ip address.

2) allow traffic from outside to this webserver

access-list 102 permit tcp any 196.35.41.82 eq 80

access-group 102 in interface outside

if you want to enable https access do the same for port 443

Regards.

Alain.
