[lacnog] IP Squatting en la region?

[Nicolas Antoniello]

Hola Carlos,

Si está detrás de un NAT (y ese es el caso acá), se me ocurre que la
única forma de hacerlo visible es utilizar algún protocolo de
Aplicación que embeba la IP original... y rezar por que no tengan en
medio (en general no se tiene cuando se trata de NATs a gran escala)
un "FIXer" en medio.

Me refiero a protocolos como SIP o alguno que sea menos "común" que
ese y que podamos esperar alguna respuesta desde dentro de la red.

Saludos,
Nico
