+
+* On Proxmox GUI, from Hardware windows edit the current IPv4 network device to IPv6 to it (only if it uses vmbr0 as Bridge, if it's on other bridge then create new network device).

+
+## Known Problems:
+
+* The host loses IPv6 address after rebooting or after some time (an hour).
+checking the interface IPs:
+```
+ip a show vmbr0
+```
+If you notice that inet6 where our IPv6 is assigned is gone, then you have this problem, to fix the issue temporary, issue new IP:
+```
+ip -6 a a 2001:bc8:50ca:101::1/64 dev vmbr0
+```
+Now test the Connectivity:
+```
+ping6 ipv6.google.com
+```
+
+Note: that you need to do this everytime you restart the host.
+
+The reason for this problem, may be due to this line in /etc/network/interfaces:
+```
+iface vmbr0 inet6 static
