VMG8825-B50B IPv6 firewall not working
Our router has just been replaced with a VMG8825-B50B firmware V5.13(ABNY.2)C0 which seems to be the latest. We have a web server and mail server which need the ports 25 and 443 open. I have done this OK for the IPv4 address with NAT, but I can't open the ports on the firewall for IPv6.
Firstly when adding an ACL rule it doesn't understand ::/0 as an IPv6 address and if I leave it blank it adds /32 to the end as if it is an IPv4 (Any/32).
I tested only opening port 25 for a specific source address and this seemed to work, but then I noticed that it had opened ALL incoming ports to the server not only 25. When deleting the ACL rule, all the ports were still open.
I had to set the master firewall settings back to Low then Medium again to fix it.
Is this router meant to support IPv6 firewall? It seems to be very unpredictable and unfinished.
