Hi,

I've configured wireless access through our ASA 5510 using the manner described here:

http://www.experts-exchange.com/Security/Software_Firewalls/Enterprise_Firewalls/Cisco_PIX_Firewall/Q_23451240.html

Everything works great, however I need to let clients on the wireless interface access the outside addresses assigned on another interface on the ASA.

I haven't been able to figure out how to do this. How do I let clients accessing from one interface get to the services hosted on another?

No, not quite. I want the DMZ users to be able to access public resources that are available through the outside interface.

For example:

AAA.AAA.AAA.AAA = Outside IP = webmail.example.com

I want a user on the DMZ to be able to access public IP AAA.AAA.AAA.AAA which is on the outside interface to access webmail.example.com.

I did some more testing and got this to work with the following.

object-group service webmail tcp
 port-object eq www
 port-object eq https
access-list wirelessdmz_access extended permit tcp any host AAA.AAA.AAA.AAA object-group webmail
