Network Throttling


Sep 16, 2021
I'm currently managing a Proxmox server with 5 Windows-10 virtual machines, each running various services such as SMB share, RDP, FTP, etc. I'm looking for guidance on how to implement bandwidth limitations specifically for SMB and FTP services to restrict read/write speeds to 10MB/s.

If i set Rate Limit (MB/s) to 10MB/s on each VM then it will limit every services. So how to limit only specific services in proxmox (based on port number or protocol) ?
there aren't any build in capabilities to throttle the bandwith of services/ports, as the throttling is handled by qemu on the NIC.
You could use a firewall to limit the bandwidth of services/ports.
