he configurado un servidor de conexiones vpn con pptp como planteo en el
asunto del correo, expongo un +/- de como se llega a este servidor
LAN --- ROUTER (cisco) --- servidor PPTP
LAN --- ROUTER (cisco) --- servidor CORREO
o sea, para llegar al servidor de vpn desde una de las estaciones de la
LAN paso a traves de un router, el tema es que desde otra maquina en la
misma interface del router me conecto perfectamente a la vpn, pero desde
las maquinas de la LAN no, me devuelve un error en el servidor de VPN

y es interesante, xq desde este servidor yo le hago ping perfectamente a
mi estacion de trabajo, q es desde donde intento conectarme!
supongo que pueda ser algun problema con este tunnel(GRE) que crea la vpn.
si alguien me pudiera dar una luz al respecto
mil gracias de antemano
