Hi

I use Cisco ASDM 5.2 for ASA when I do configuration..

How I can allow connection from outside to dmz ex. HTTP server??

I have static IP which come from ISP by PPPoE..

Error is:

TCP access denied by ACL from 85.77.230.115/41833 to outside:213.139.xxx.xxx/80

My config is now:

i am no expert but it looks like acl does not permit any access to outside.

try tunning [code:1]access-list acl_ouside permit tcp any host 213.139.xxx.xxx eq www[/code:1]

Your outside interface statically maps to the DMZ interface? Is that the intent? Or is there a server inside the DMZ?

Hi

Okey..

I put to access-list...
access-list outside_in extended permit tcp any host 213.139.xxx.xxx eq www

Still I get error:
TCP access denied by ACL from 85.77.243.57/50258 to outside:213.139.xxx.xxx/80

I have HTTP server in DMZ.

I'm not sure that NAT, need I that?

AND I'm not sure that ASA 5505 hardware is that right hardware for that situation.

This statement is not correct. You are mapping a public ip to the DMZ interface with this statement. Replace the IP address 192.168.50.10 with the ip address of the dmz web server.


static (dmz,outside) tcp 213.139.xxx.xxx www 192.168.50.10 www netmask 255.255.255.255

Please try the following:

no static (dmz,outside) tcp 213.139.xxx.xxx www 192.168.50.10 www netmask 255.255.255.255

static (dmz,outside) tcp interface www 192.168.50.10 www netmask 255.255.255.255

I assume that the IP 213.139.xxx.xxx is the interface IP so it is safe to use the keyword interface on the static NAT that you have. If that doesn't work it could be due to the fact that you have a ASA 5505 with a base license and normally the DMZ is fully usable with a security plus license.

Try it out and let me know if that works. If that doesn't I can look for the link that talks about the license.
