TrueNAS runs at 1 GB instead of 10 GB

Hello everyone,

I'm new to Proxmox and happy that I got everything up and running.
Now my issue is that Truenas runs only at 1 GB. When I connect the PC and the Proxmox (both Intel 10 GB) they run at the max. speed.
My config:


enp2s0 is the 1 GB Router, enp5s0 the 10 GB Line.

Any ideas? Do I need to do some shell tinkering?
Any help is appreciated


PS: TrueNAS:
