Feature Request: Add Gateway Specification Question for Installation Script

[SunFlowerOwl]

Description

When configuring a vmbr1 interface with NAT on the Proxmox host, it is necessary to specify the gateway during LXC installation. Currently, the installation script does not prompt for the gateway. The gateway should be set to the Proxmox host IP that handles the NAT.

Proposed Feature:

Add a question in the installation script that allows the user to explicitly define the gateway IP. This will ensure proper network configuration for LXCs using NAT on custom bridges like vmbr1.

Use Case:

User sets up a VM or LXC on vmbr1 with NAT on the Proxmox host.

The LXC requires the gateway to be the Proxmox host IP for proper external connectivity.

Without this option, the installation script cant suceed:

Workarround:

Install with vmbr0 with host gateway to have Internet access and after switch to vmbr1

Benefit:

Simplifies LXC network setup on NAT bridges.

Reduces manual configuration and potential networking issues.

Makes the installation script more flexible for custom network setups.

WDYM it doesnt ask for gateway? The defaults install mode doesnt ask anything, it uses defaults. Advanced mode asks you for every detail needed to make a container
