I had a power loss this morning for a few minutes, when everything came back online I had this weird issue with Proxmox where all VMs, including the host has a weird internet issue.

There is v4 and v6 connectivity. However, when downloading/uploading anything using IPv4, the connection "establishes" but then drops to 0. For example, using wget or curl to download anything from anywhere, it starts with 50 KB/s, downloads for one second and then immediately drops to 0 KB, but does not error out.

IPv6 with router 6in4, seems to work just fine. So something seems to be broken with Proxmox IPv4.

This only happens on Proxmox, Desktop PC in the same network can do 1 Gbps download and 50 Mbps upload easily. (ISP package)

Any ideas?
