How to redirect from ip address (ip:port) to domain and subdomain?

Question

Apache HTTP Server

I have a server on it I installed OpenMediaVault. On OMV, I installed various services and services: Nextcloud, Emby, etc. Each has one ip and a different port in order to be able to use it. I screwed the domain, how can I redirect from each ip to my subdomain? For example, ip 192.168.0.1:1234 to the subdomain webapp.domen.ru or domen.ru/webapp. And so for each ip.
