Userspace-networking mode - how to guides


i am looking for a details faq/how-to guide.
i did read

so i have a bunch of basic questions before i go down this path.
sure other have or will soon have these basic questions and looking for working examples.

  • for a node using userspace-networking, i can make outbound connections to other ts nodes.
    but what about inbound connections? can other ts nodes connect to services on that userspace node?

  • does that node have a tailscale name/ip in the web admin console?
    can i apply access control?

  • can i ssh into that userspace node?

thanks much,
