Installation of Pihole, IOBroker, Nextcloud and Portainer

Good evening,

if got some kind of problem with the setup of docker.

The installation of the container worked perfectly fine. Could access the admin panel of Pihole and nextcloud. But nextcloud throw network errors and pihole had the ip as the device ip.

Id love to access the panels by separate ips. Like nextcloud, pihole and so on. Because i cant set a ip with a port as a dns in my router or?

Big thanks!
