Hi friends,
I have a Firewall 5520 with 3 interfaces: Inside (Host: 172.16.10.0/24 and GW: 172.16.10.2) Outside (119.202.193.81) and DMZ (182.16.10.1)
I did connect LAN cable on the Server (182.16.10.99) direct to GigabitEthernet0/2 on Firewall ASA 5520.
I have 2 questions:
Can I connect direct with LAN cable 5e from a Server to the Firewall and the Led alert (Red) is correct? I can Ping to 182.16.10.99 from any hosts placed in the Inside interface. But the strange is Ping is successful to any IP starting with 182.16.10.x (but can not Ping to 182.16.10.1 is the IP of DMZ interface, and I only have one Server (182.16.10.99) connected direct to DMZ Port but the Ping replied successfully with any IP starting with 182.16.10.x (except 182.16.10.1)
I want any Host Inside access to Server 182.16.10.99 and versa (both way)
Any ideas, please help, tks a lot !!!

Thanks all. The DMZ Interface status Down may be related to the cable (maybe it needs cross cable because the DMZ port connects directly to the Server's GigabitEthernet port). So I will try to seek help if needed. Thank @MHM Cisco World & @Sheraz.Salim again!!!
