🌟 Briefly describe the feature

Option for Address Management with IPv6

📝 Detailed description

in advanced settings I get ask for a lot of details for the IPv4 connection. there I can choose the type for the address management and its defaulted with dhcp. I dont get the very same option for IPv6 address management so the PXE default setting is untouched with "static".
I also want the option to change it for IPv6 - in a best case scenario that setting is defaulted with SLAAC (also for basic setups).

💡 Why is this useful?

I request this feature because I get some strange output when running e.g. the pihole instal script:

✔️ Set up Container OS
✔️ Network Connected: xxx.xxx.178.100 xxxx::xxxx:xxxx:feae:8c22 xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:feae:8c22
✔️ IPv4 Internet Connected
✖️ IPv6 Internet Not Connected

that is because I need to change it to SLAAC for a working IPv6 connection.
To get the script to check the IPv6 connection successfully I need to be faster, changing that setting in the UI after the container gets created by the script, than the script is to do this very check.

With https://github.com/community-scripts/ProxmoxVED/pull/34 I added IPV6 to our dev repo. Can you head over there and try with a script if it works? I dont use IPV6.

Sorry, maybe I didn't understand what to do.
For testing I just used
https://raw.githubusercontent.com/community-scripts/ProxmoxVED/refs/heads/main/ct/debian.sh
and on default mode I git the usual message - the setting on network was untouched.
and on advanced mode I didn't realise any new option.

can you pls give me an instruction how to test this?

@Tinsus, sorry for the delay, ive checked the function and reworked it.
Its only on dev-System, so can you take a look & maybe give feedback?

bash -c "$(curl -fsSL https://raw.githubusercontent.com/community-scripts/ProxmoxVED/main/ct/debian.sh)"

Default Settings -> auto enabled slaac
Advanced Settings -> choose between static, dhcp, auto (slaac) and none

Generally speaking, should slaac / auto really be active in every default setting? Or would you prefer “none” with optional variable transfer?

Thanks for your work.
I just tested that script.

First of all: with the default settings the IPv6 (using 1 as first input) selects static.

Using the advanced settings (3 on first input) and than only using the default values does exactly what I intended to reach by creating this ticket.
I got this error on my first try:

✔️ Started LXC Container ⠦ Customizing LXC Container [ERROR] in line 1279: exit code 0: while executing command pct exec "$CTID" -- bash -c "echo $tz >/etc/timezone && ln -sf /usr/share/zoneinfo/$tz /etc/localtime"

but with a very new try (again: first 3, than enter only) everything works great.

your question:
I run an IPv6 internally because I only see benefits doing that. My router doesnt need to use any funny tunneling-stuff with internal ipv4 internal traffic to the external ipv6 world. with my network SLAAC is the way also includes any LXC/VM to that very mindset. So for my egoistic view: yes, I would prefer SLAAC being the default for every default setting - because in none-ipv4-networks it simply gets ignored(?).
