Promox Network Interface

[saffiulah dost]

At the moment I’m setting up a homelab at home and I have a question about it. Maybe you have an idea.


I have a Fujitsu server with two Gigabit Ethernet ports as well as an iRMC port as a management interface. Proxmox is installed on the server. One of the network ports has the IP address 172.16.14.1/24 with the gateway 172.16.14.254. This port is connected to the internet, and via this IP address I can access the Proxmox web interface from my laptop.


However, the problem is the following:
If I assign a VM (e.g. Windows Server) the IP address 172.16.15.10, this VM has no internet access. The VM is completely isolated and has no external connectivity.
English translation:

I would be very happy if someone could help me.

Hi,

If I assign a VM (e.g. Windows Server) the IP address 172.16.15.10

(assuming also a /24 like the other,) do you have a gateway for this network?
172.16.14.0/24 is one subnet, 172.16.15.0/24 a separate one. So essentially you need some router for this subnet.
This isn't really specific to Proxmox VE, but standard networking

Depending on your needs, you can, for example, create a "Simple" SDN zone and then create a VNet with SNAT enabled on it. Or do it via some external firewall/router/etc.
