I have two router to build my own DMZ:
Router 1 (Cisco RV110W) connected from Internet to DMZ:
WAN IP: 80.21X.XX.XX
LAN IP: 192.168.1.1
Router 2 (Cisco RV810W) connected from DMZ to LAN:
WAN IP: 192.168.1.101
LAN IP: 192.168.2.1 / 255.255.255.0
I have a WebServer (IIS, 192.168.1.103) in the DMZ. I can see (ping, RDP) this server from my LAN, but the WebServer can't see anything inside my LAN. That's OK so far.
Now I have a NAS Devices (192.168.2.222) inside my LAN and that is configured to be an FTP server. How can I give access to this Device from Internet / DMZ?
