I'd like to validate/get feedback of my mini project.
Goal:
A Docker image that bridges Windows 98/DOS era computers with a modern Linux NAS using focusing on security:
Samba 4.16.11 — the last version supporting SMBv1/NT1 (required by Windows 98), served as a read-only guest share. No attack vectors for virus or drunk retro PC users. Also modern NAS drives have COW file systems with snapshots for extra safety.
vsftpd — an FTP server for uploading files from retro machines to the same shared directory.
The container runs on a dedicated docker macvlan network mapped to a physical NIC, giving it its own IP address on the retro network while keeping it completely isolated from modern services on your main network.

If you have modern NAS and are ready to add additional NIC, can be USB LAN adapter for ultimate isolation then this might be for you. Link: https://github.com/vutt-code/retrosamba416 Some assembly is required.
Any comments on concept and delivery? Feel free to browse code on github.
