Setting Up a Second FTP Virtual Server on Proftpd

[Drek]

I want to set up a second FTP virtual server to host backups from my router. I only want it to be accessible from my lan. I'm wondering if anyone could give me some pointers on how to do this. It needs to be an ftp server because that is what the backup package for my router requires. Here is my current working configuration. I tried basically copying this and changing the port and I couldn't get it to work. If you could point me to some intelligible documentation, or share with me a working configuration, I would be grateful.

<VirtualHost ftp.domain.com>

	ServerName		"User FTP Server"

	MaxClients		8
	MaxLoginAttempts	3

	DeferWelcome	on

	<Limit LOGIN>
		AllowAll
	</Limit>

	<Directory /homedirectory>
		HideUser	root
		HideGroup	root

		<Limit READ WRITE DIRS>
			AllowAll
		</Limit>
	</Directory>

</VirtualHost>

Somehow I managed to chroot the above user, but I'm afraid I can't even remember how I did that...
