servidor vpn
buenas lista, ay en un estado de desesperación no tengo más que esperar sus conocimientos (eso ya que lo he googleado todo).
el problema es que no puedo configurar correctamente un conexión vpn de windows a debian lenny con pptpd, el comportamiento ha sido extraño ya que en momento si conecta y funciona a la perfección, pero en otros se cae y no hay caso.... creo haber identificado el problema buscando por todos los log
Mar 5 11:20:55 SERVIDOR pptpd[10049]: GRE: read(fd=7,buffer=80505a0,len=8260) from network failed: status = -1 error = Protocol not available
Mar 5 11:20:55 SERVIDOR pptpd[10049]: CTRL: GRE read or PTY write failed (gre,pty)=(7,6)
(estas 2 lineas son sacadas del syslog en un intento de conexion, es donde creo esta el problema)
espero alguien me pueda ayudar... lo más raro es el comportamiento ya que funciona en ocasiones... mmm otra cosa ya intente abriendo puertos en iptables pero no creo que sea eso, o puede que algo me falte algo... debo agregar que el servidor linux (donde esta el vpn) comparte internet tb dejo el scrip por si me falta algo
echo 1 > /proc/sys/net/ipv4/ip_forward
iptables -F
iptables -t nat -F
iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -d 0.0.0.0/0 -j MASQUERADE
iptables -A INPUT -p TCP -m state --state RELATED -j ACCEPT
les dejo el syslog completo del intento por si hay algo más que pase por alto
