Since this is internal traffic and not external traffic, the firewall cannot be configured for vLANs. Use a solution at the operating system level for this purpose.
Assigning Cloud vLAN
Learn how to assign a Cloud vLAN to your server.
1. Getting Started
- Make sure you have a Cloud vLAN product: https://www.netcup.com/en/server/kvm-server-extensions
- Note that the Cloud vLAN must be configured at the same location as your server.
- Once the booking is complete, a button will appear in the Server Control Panel (SCP) under Network.
2. Opening the Server Control Panel (SCP)
- Log in to the Server Control Panel (SCP).
- Select the server to which you want to add a vLAN.
- Go to the Network menu item.
3. Adding vLAN
- Click Add Interface at the top right.
- Select the desired vLAN from the list.
- Select a driver.
- Click add.
- The vLAN will then appear as a new interface at the top right. In the settings, you can rename it, change the driver, or delete the vLAN.
4. Configuration at Operating System Level
- Check whether the network interface is available. On Linux systems, you can usually verify this using
ip a. - If the interface isn't listed there, restart your server or check via the rescue system.
- Configure at the operating system level which traffic should be sent over the VLAN. Follow the instructions provided by your operating system and applications.
