Hi for a new host in original lfs need open ports router?

Hard to understand what you need, but I guess you need to know which ports to open when creating a host from your PC?

By default it's 63392.

yes need open ports or only open in lfs server?

You need to open the port 63392 in your router.

Also add the LFS.Exe ( DCon.exe ) as an exception in the Firewall in case it's enabled.
