Ahhh ... the server is multihomed, and I am using the secondary NIC for the DMZ. The two interfaces on the server are not on the same subnet. I will check the gateway address. Thanks for your help. I will let you know if it resolves the problem.

Thanks! The server is using two interfaces, and the DMZ connection is set to use the secondary NIC which is not on the default gateway of the firewall interface. Changing the web server to use the DG of the DMZ firewall interface solved the problem. Thanks!

Simply trying to hit a web server on the inside of the network. Seeing the following syslog message on the firewall ... &quot;Built inbound TCP connection 2067 for outside:38.101.218.165/306<wbr />44 to dmz:192.168.177.10/80&quot;<br />

Cisco ASA not handling NAT traffic properly for internal web server

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
