Título: Conexiones por UDP y Proxy bypass Saltar restricciones
Publicado por: andreker en 26 Noviembre 2011, 21:10 pm
Hola, tengo una duda, estoy tras un proxy bien restrictivo, pero usando el servicio de yourfreedom he podido conectarme usando UDP en el puerto 53 a sus servidores y atraves de esa conexion abro bien o un puerto socks o una conexion vpn, hasta ahi genial, pero yourfreedom da poco tiempo de conexion... 6 horas al dia...
alguien sabe de otro servicio igual o parecido, o
al parecer las peticiones udp no pasan por el proxy y estuve imaginando que podria hacer una conexion vpn por udp y navegar por ahi, que opinan... me gusto mucho la experiancia vpn pues no tuve que estar proxificando todo, pero lo mas importante aqui es saltar el proxy que es restrictivo al puerto 80
alguien sabe de proxys o semejantes que usen udp...
Gracias

Claro, ya eso lo he hecho, pero eso es por tcp, y tengoq ue usar el proxy, mi idea es usar ul udp que no pasa por proxy y conectarme a algo tipo vpn o algo asi, o tu me dices conectarme a ssh por udp?

listo dos cosas solucionadas... 1.No conectaba usando proxys configurandolos por el GUI de openvpn, toca poner la opcion socks-proxy <ip.del.proxy> <puerto> en el archivo ovpn y ahi no me dio problemas y se conectó, solo que al conectarse me corto la conexion del proxy que es un tunel ssh, parece que por que hizo que todo saliera por el vpn y ahi mato la conexion del ssh, eso ya es otro tema aparte que me tocara solucionar luego. 2. ya pude conectar por udp, al parecer es que no todos los servidores que dicen estar funcionando realmente lo estan, y algunos tiene filtros, me he podido conectar al de AirVPN.org ero no me he podido loguear por que no me dejan bajar los cert keys y ca, suppongo que con un poco de espera ... Bueno , si alguien sabe como conectar la vpn y especificar que me respete la ruta que uso para el ssh que me ponga un link, que ya estoy astenico de tantas busquedas Gracias
