Cisco ASA- NAT and ACL

[rjanakan]

Hi,

I'm testing a Cisco ASA 5510. I'm new to PIX and using ASDM to configure it. I configured a static NAT to map a public IP to private IP. I configured ACLs. When I hit the URL from public IP, I can see the NAT happening at ASDM sys log window. But I can't see the page and after 30 seconds the connects drops with SYN timeout.

Any thoughts??

Thx in advance,
Regards,
JR

Are you seeing hits on the access-list entry that allows the traffic you are attempting?

It may be a routing issue. Are there appropriate routes on the host as well as the firewall?

Some more detailed information would probably be helpful.

Dozier,

Thanks for your reply.
I can see inbound TCP connection established with webserver after xlation. But no outbound connection is getting established. Both Public IP and Private IP are directly conected interfaces. Do I still need routing?
Please find my configuration below:

I saw your other thread and replied after I did this one, so let's stick with the other thread now.
