Bien, he instalado un debian lenny 5.0 desde cero actualizado etc.. le
he puesto otra eth (eth1) para poder escribir en la lista y hacer las
pruebas en este mismo
y tengo conexión a traves de la localnet usando un proxy que tengo en
otro servidor windows el cual sale por esta misma red 14.15.16.1
El servidor anterior le he puesto otra vez la ip de jazztel porque no
podemos estar sin correo, y pues ahi esta funcionando como siempre,
todo bien.
No obstante este linux recien instalado en otro ordenador, tiene el
mismo problema que el servidor que quiero migrar a esta ip, cero
conexion a 14.15.16.1
El escenario ahora mismo es el siguiente.
Router telecable -> switch -> y a este switch tengo conectado:
1- linux recien instalado en otro pc para las pruebas con esta nueva ip.
2- cable a un switch donde tengo los demás servidores. windows/linux
