How it works
Targets Proxmox VE 7 and 8 with the default Linux-bridge networking model only, not Open vSwitch and not Proxmox SDN. It renders the same /etc/network/interfaces stanza the Proxmox VE web UI writes for a bridge: physical port stanzas, then the bridge itself with bridge-ports, bridge-stp, bridge-fd, and, when enabled, bridge-vlan-aware with a full bridge-vids 2-4094 range. A VLAN-aware bridge is expressed with bridge-vlan-aware, not a separate VLAN sub-interface, so this tool does not expose the shared VLAN identifier fields at all. Only one static address per family is supported, matching ifupdown's own stanza model.
Proxmox VE stages changes in /etc/network/interfaces.new and only applies them on reboot or ifreload -a; this tool never edits that file, runs ifreload, or contacts a node.
IPv6 "Not configured" writes no inet6 stanza for the bridge; it does not turn IPv6 off. The bridge's IPv6 is then left to its kernel sysctls. Under the kernel defaults (disable_ipv6=0, addr_gen_mode=0, accept_ra=1, autoconf=1, forwarding=0) it gets an IPv6 link-local address and accepts Router Advertisements and SLAAC. Sysctls changed on the node decide instead: accept_ra=0, or forwarding=1 without accept_ra=2, ignores Router Advertisements; autoconf=0 stops SLAAC; disable_ipv6=1 or addr_gen_mode=1 leaves no link-local address.
Proxmox VE's ifupdown2 3.2.0-1+pmx4 and later (shipped for Proxmox VE 8 and later) also sets the bridge's accept_ra and autoconf to net.ipv6.conf.all.accept_ra and autoconf when the stanza does not set them. Proxmox VE recommends keeping its IPv6 defaults; its admin guide (Disabling IPv6 on the Node) turns IPv6 off for the whole node with disable_ipv6 sysctls. This tool writes none of these sysctls.
