Web UI in IPv4 and IPv6

Hi
I try to activate the Web UI in IPv4 AND IPv6.
I found this page https://pve.proxmox.com/pve-docs/pveproxy.8.html to enable IPv6.
So I created a /etc/default/pveproxy file and put in it :
LISTEN_IP="2a01:e0a:a:b::c"
I restart the service with :
systemctl restart pveproxy.service spiceproxy.service

But in this case, the IPv4 is not working anymore (of course).

My question is : how should I put "::" to activate both, and request the daemon to listen on all the IP available ?
I also try "::" and "::ffff:0.0.0.0", but they activate only IPv4.

Thanks

What's your Proxmox VE version pveversion -v ?
As since Proxmox VE 6.4 the pveproxy main API daemon listens on both per default, so you'd just not set the LISTEN_IP variable there at all, but yes, using the :: wildcard (with PVE 6.4 or newer) would make the API proxy listen on both, IPv4 and IPv6.
 
# pveversion -v
proxmox-ve: 6.4-1 (running kernel: 5.4.157-1-pve)
pve-manager: 6.4-13 (running version: 6.4-13/9f411e79)

I will try to upgrade in version 7 to see if the problem is solved.

The full output of that command would be interesting to ensure no dependency is outdated/held back, as the change needs also newer libhttp-server and libpve-common packages IIRC, the manager version itself should be recent enough.

Just to be sure: How do you check where the web.interface listens (not that it's a FW issue), e.g., can you post the output of:
Bash: 
ss -tlpn

Seems working just fine?

If you do force an IPv6 it listens just on that ([2a01:e0a:2a7:9cd0::99]:8006):

And if you do not force any explicit IP it listens on the full wildcard (*:8006):

So the "listen on both" definitively works from the PVE API daemon point of view, if you still cannot connect via a specific IP version I'd check firewall/network.
 
Hi Thomas
After upgrading to proxmox 7, the problem disappears. I can connect to the interface by IPv4 and IPv6

Thanks a lot !
