Low Upload Speed

[andrema2]

So, this is a weird situation.

I have a virtualized OpnSense under Proxmox. In fact they are two acting as HA. Last week I had a hardware failure on the main OpnSense and had to change the hardware. I returned the backuped VM on the new HW and it appeared to be fine.

When I checked the upload speed it is not going beyond 40 mbps, it should be 150 mbps. The download speed is fine at 350mbps. It showed me that the speed of the virtual NIC seems to be ok.

I entered in Temp Maintenance mode and the secondary OpnSense can upload up to 150 mbps. So, there is no problem at the ISP side.

I don't know what is going on. How can I solve this problem ?
