Hello,

I decided to upgrade myself from 1gbps interface to 2.5gbps by getting Alfa AUE2500C Ethernet Adapter.

Network config:
Code:
auto lo
iface lo inet loopback


iface eno1 inet manual


iface enx00c0caa917b5 inet manual


auto vmbr0
iface vmbr0 inet static
        address 192.168.1.250/24
        gateway 192.168.1.1
        bridge-ports eno1
        bridge-stp off
        bridge-fd 0

After changing line "bridge-ports eno1" to "bridge-ports enx00c0caa917b5" and performing reboot, I was able to ping everything from the host.
From Guest however, I was only able to ping other Guests and Host, but not Gateway or WAN.

Any suggestions?
 
Please provide the output of pveversion -v and ip -details a
As well as the journal from the last boot: journalctl -b

This is where you switched back to eno1? Could you provide the output of ip -details a when the USB NIC is in use again as port for vmbr0?

Could you see if the issue persists with kernel 5.11? You can install it by running apt install pve-kernel-5.11
