I have a Proxmox VE server connected to a home router on
Below is my
vmbr0. Both the router and my ISP supported ipv6 so other devices connected, and all VMs/containers bridged to this router can access remote ipv6 addresses such as 6.ipw.cn (ipv6.google.com is unreachable due to regional network restrictions). But I was told that the network is unreachable while trying to ping and curl that working remote ipv6 host. It seems that this pve server has got its own ipv6 address according to ifconfig:
