when in LFS I click on Start on "new host" In the Master Server does not appear why?

because LFS does not do UPnP (which is a standard since 10 years) and people have zero knowledge about opening network ports on routers nowadays. search on forum, there are dozens of topics about this already

you can help me for open server?

Login to router forward insim and gameport to your pc.


Edit: https://en.lfsmanual.net/wiki/Hosting

or already run this guide but the server will not start

Give us more info then what u did. Show some screenshots router for example.

Port Forwarding / Home Routers
There are quite a lot of home routers out there, so giving a guide for them all would be quite difficult. Heres one for DD-WRT (I run a linksys WRT54G).
Open a browser window, and goto your router's IP address. In most situations you'll find this is your default gateway. You can find this by going to Start > Run, typing "cmd", clicking ok, and then typing "ipconfig" and pressing enter.
Click "Applications & Gaming"
Click "Port Forwarding"
Click Add
The following settings should be enough: Application = LFS, Port From = 63392, Protocol = Both, IP Address = Your Local IP Address (can be found from ipconfig, as above), Port to = 63392, and tick Enable.
Click "Save Settings"
