hola lista

veran tengo un problema con un tunel via linux debian, anexo los
archivos de configuracion al final

pptpd.conf
options
pptpd-options

y las versiones de los paquetes pptp ppp y kernel

como enlace a internet esta un speedstream con port forwarding el 1723 y
el 47, hacia el linux


cuando logra enlazar, trabaja bien, entro a la red, accedo al un
"*indows 2003 server" y a la aplicacion, el "ifconfig -a" manda esto:

ppp0      Link encap:Point-to-Point Protocol
          inet addr:192.168.100.243  P-t-P:192.168.100.180
Mask:255.255.255.255
          UP POINTOPOINT RUNNING NOARP MULTICAST  MTU:1400  Metric:1
          RX packets:61 errors:0 dropped:0 overruns:0 frame:0
          TX packets:35 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3
          RX bytes:5988 (5.8 KiB)  TX bytes:3254 (3.1 KiB)

cuando intenta enlazarse y no lo logra manda esto:

ppp0      Link encap:Point-to-Point Protocol
          POINTOPOINT RUNNING NOARP MULTICAST  MTU:1400  Metric:1
          RX packets:61 errors:0 dropped:0 overruns:0 frame:0
          TX packets:35 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3
          RX bytes:5988 (5.8 KiB)  TX bytes:3254 (3.1 KiB)

donde se observa que no aparece esta informacion

          inet addr:192.168.100.243  P-t-P:192.168.100.180
Mask:255.255.255.255
          UP

revisando el log, la diferencia que observo es la siguiente entre uno y
otro enlace
