IP Masquerading, error en



-----BEGIN PGP SIGNED MESSAGE-----


	Hola, vereis, tengo un problema. He montado una LAN, utilizando debian
como gateway, pero fijaros que pasa si intento acceder a cualquier servidor de
ftp, independientemente de si es anonimo o no, desde una maquina directamente
conectada al gw.

# ftp ftp.isc.org
Connected to isrv4.pa.vix.com.
220 isrv4.pa.vix.com FTP server (Version wu-2.6.0(1) Tue Nov 30 17:39:57 PST 1999) ready.
Name (ftp.isc.org:root): anonymous
331 Guest login ok, send your complete e-mail address as password.
Password:
230 Guest login ok, access restrictions apply.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> ls
500 Illegal PORT Command
ftp: bind: Address already in use
ftp> ls

	Bueno, utilizo un kernel 2.2.4-1, el que venia con la distribucion de
la slink, y he seleccionado estas opciones segun he leido en varios HOWTO's,
documentos etc.

  x x[*] IP: masquerading                                              
  x x--- Protocol-specific masquerading support will be built as modules.
  x x[*] IP: ICMP masquerading                                     
  x x--- Protocol-specific masquerading support will be built as modules.
  x x[*] IP: masquerading special modules support    

Utiliizo ipmasq Version: 3.2.5 para inicializar las reglas de ipchains, pero el
error no cesa, es problema del bind?, de las opciones?  tengo que modularizar
las opciones en las que pone "rotocol-specific masquerading support will be
built as modules."?
	A ver si alguien de la lista me puede echar un cable.
