ext_if="em0"

ip_ext="*.*.*.*"

ip_jail="127.0.0.3"

rdr on $ext_if proto tcp from any to $ip_ext port 21 -> $ip_jail port 21
rdr on $ext_if proto tcp from any to $ip_ext port 49152:52000 ->  
$ip_jail port 49152:52000

pass in log quick on $ext_if proto tcp from any to $ip_jail port 21  
flags S/SAFR keep state

pass in log quick on $ext_if proto tcp from any to $ip_jail port 49151  
 >< 52001
pass out log quick on $ext_if proto tcp from $ip_jail port 49151 ><  
52001 to any

No log do proftpd apenas surge isto quando acesso via browser:

Sempre que acedo via firefox ou IE não consigo abrir o FTP, ele mostra  
a janela de login mas depois devolve 1 mensagem onde diz que para  
verificar as permissões da folder e que a ligação ao servidor não é  
possível.

drwx------   3 teste  wheel  512 May  8 18:48 teste

Contudo, se aceder via ms-dos

fazendo ftp
open *.*.*.*

ele pede o login e abre o FTP.

Na firewall nao vejo nada a ser bloqueado...

Alguma ideia?
