Cisco ASA 5510 - DMZ Web Server help!

[red_day14]

I hope I can get some help about my issue.

I've configured the dmz on my web server, but I can't access  from outside network!! So, from DMZ port I have another switch where I have other pc and my web server, from the pc that are in the same switch I'm able to go the web server, but not from outside network!.

Here are the commands that I have used for dmz, so my dmz name is dmz1 and the port that I assigned is eth 0/3, and the IP 192.168.20.1

I really would appreciate if somebody helps me.

Hi,

As per the description, your server is behind 'dmz1'. As you want to access server from outside, i could not found any 'static nat' referring your server.​

please configure the same :

static(dmz1,outside) <mapped-ip> <static-ip> netmask 255.255.255.255

-Also configure access-list to allow outside traffic to go to web server. Place the same on Outside interface.

access-list out_in permit tcp any host <private-ip-of-server> eq 80

access-list out_in permit tcp any host <private-ip-of-server> eq 443

access-group out_in in interface outside

Please let me know if you have any queries on this. If this answers your query, I would request you to select the appropriate response as the solution for this thread. 

Regards,

Akshay Rastogi
