Static NAT Problem

Unanswered Question

I am trying to map a Public IP to private Virtual IP on the load balancer which forwards the traffic to web servers.

I have done all the necessary configurations on ASA, but the web service is still not accessible from the internet.


Outside IP:

Inside IP (VIP):

static (inside,outside), netmask

access-list outside_in extended permit ip any any

access-group outside_in in interface OUTSIDE

The web service is accessible locally on IP. While I am accessing via the public IP over the internet I can see following on 'sh conn' display

TCP out in idle 0:00:02 bytes 0 flags AX

What could be wrong. Please assist.

Does your load balancer have a default route going out?

Yes. The default route is present.

I didn't mention earlier that the ping to public IP over the internet is successful. I have also configured the load balancer for ping requests.

Any other clues.

When the NAT translation dies, what is the byte count? I assume you have hit counts on your ACL?

Yes. There are hit counts on the access-list for every hit via the browser. Something like 0xd1647829.

Maybe a packet cpature between the two (or on the pix/asa) will shed some light. From the firewall you can ping the VIP correct?

Yes. I am able to ping the VIP from firewall.

I will try the capture tommorow. In the meanwhile any other suggestions will be great.
