No you must not. America First! 
Ah ok!
The following structure FritxBox ports 443 and 80 forwarded to -> Ipfire-red -> Nextcloud orange not available!
I have the following problem, if I have my Nextcloud in the red network (Fritz-Box), it can be reached without any problems.
Unfortunately not in the orange network.
Do you have to create a firewall rule or why not come to orange (DMZ)?
Firewall options are FORWARD blocked and OUTGOING allowed.
Greetings Micha
My humble opinion:
When using nextcloud privately, put it behind a vpn for security reasons.
Otherwise you have to think massively about securing the server.
I want to rub Nextcloud in the orange (DMZ) network, because of that it fails.
… Godda feed mo’ info, maaan…
for an example from the old forum: IPFire Community
please note: This is Read only.
You will need to have port forwarding twice:
First in your FritzBox: Port 443+80 --> Static IP of the IPFire RED interface
Second in IPfire with firewall rules: Port 443+80 --> Static IP of your nextcloud server in ORANGE
That’s it.
Thanks for the help, I think it’s a little worth it …
