How to block ALL IPv6 traffic for a VM using ONLY the Proxmox GUI?

[Blipt]

Hi everyone,

I’m trying to achieve a VM‑wide IPv6 block in Proxmox using only the GUI, without manually editing:

/etc/pve/firewall/<VMID>.fw

I want the GUI rule to behave exactly like the manual rules:

IN  -6 DROP
OUT -6 DROP

These two rules correctly block all IPv6 traffic, including:

• TCPv6
• UDPv6
• ICMPv6
• ND / RA
• Multicast
• Everything in the IPv6 family

Is this enough?

hmm, just set the policy to DROP maybe? and disallow everything.. but at that point, why even connect the NIC?
EDIT: Ah, because you want IPv4 only heh. Well, I'm not sure you need ipv6-icmp if you block ipv6, it's enough for me (and do not allow NDP/RA).
