Hallo my Englisch is very bad!!!
I hope someone can help me or give me a few tips.
I have a FritzBox at home that operates DHCP: 192.168.1.0/24 in this network is my server with Proxmox 192.168.1.100. I want to create a DMZ on the server with two firewalls. The DMZ should be 10.0.0.0/29 so 6 clients. In the DMZ there is a DNS that is supposed to communicate in the subnet 192.168.1.0. So port 53 for DNS and actually 80 and 443 for HTTP and HTTPS. I have already tried several variations.
IPFire RED and Green Zone, in the RED my DMZ and Green was my LAN but despite routing and rules I had no access to the Internet from the DMZ in the Green Zone 192.168.1.0.
I then tried IPfire with three zones, i.e. RED Green and Orange. Orange was my DMZ and Green LAN. Again no communication from the DMZ to the LAN. thank you for your help
