Title: Proxmox / Opnsense : download at 1Mbps
Post by: Tryndie on April 10, 2025, 06:56:56 PM

Hello,
I installed opnsense 25.1 on a VM on a dedicated server at OVH.
My proxmox and all Debian VMs download in 1Gbps.
Opnsense blocks on 1Mbps.
If I make an iperf, I have 1Gbps up/down.
If I make a wget I stay at 1Mbps.
All the traffic behind Opnsense is necessarily restricted.
I tested with FreeBSD latest version and I have 1Gbps up/down.
I set up the network card in VirtIO in VM with qemu-agent.
Network card model of server : Broadcom Inc. and subsidiaries BCM57502 NetXtreme-E 10Gb/25Gb/40Gb/50Gb Ethernet (rev 12)

Any idea ?

Thanks

Yes. See this (https://forum.opnsense.org/index.php?topic=44159.0), notably the network hardware section on Broadcom adapters.
