access to container proxmox from dyndns domain from internet

[aboooodaj]

Hi,
I have a problem trying to access the container through an external connection using a domain name (by dyndns)
I usually do this by opening a port on my router, for example 100, and connect like this
mydoman.com:100
And proxmox has another port number which is 8006 use like this
mydoman.com:8006
How do I access the container this way


This is a picture of the network setup

This is a picture of the router setup
I'm new to this, please help

From a security standpoint it would be better not port-forward your PVE webUI but use a VPN tunnel instead, if you want to manage your PVE host while not at home.

You enabled the PVE firewall for the LXC. Did you add a firewall rule to allow port 100 for incoming connections? By default all incoming connections will be dropped.

And you are sure your port-fordward is really working? "0 aktiv" in your routers webUI sounds like it isn't used yet.

Yes, these are the proxmox settings and it works fine

Looks like a Fritzbox. What service are you trying to run on on port 100? You have chosen "HTTP-Server" which is a preset for web servers. If you are running something else, like a game server, you might need to select "Andere Anwendung" and then select the correct protocol (TCP/UDP/ESP/GRE).
A service running UDP for example shouldn't work with "HTTP Server" selected which should use TCP as protocol.

And you are sure your ubuntu server doesn't got it's firewall enabled? You can check it with sudo ufw status.
If it is enabled you would need to allow port 100 like this: sudo ufw allow 100/tcp.

Can you access your Nextcloud from LAN by using http://192.168.1.20:100?
Did you edit your Nextclouds config.php to allow your DynDNS Domain in its "'trusted_domains'" in addition to the local IP? Otherwise requests might get port-forwarded to your LXC but nextcloud is dropping them because they didn't come from a trusted domain.

Yes, the firewall is enabled and the port is working fine http://192.168.1.20:100
