Pérdida de paquetes UDP entre dos conexiones Vodafone HFC coaxial con Fi

1
Jeronimo17

⋮

Uso OpenVPN entre 2 router con 2 conexiones Finetwork (ambas Vodafone HFC coaxial 120/100 Mb/s) entre mi casa y la de mis padres, y llevo desde hace por lo menos un par de días que notaba tirones al conectar por ssh y pérdidas de la voz momentáneas en llamadas VoIP entre ambas conexiones.

He analizado con iPerf3 entre ambos extremos y con TCP no hay problemas pero con UDP a veces se pierden el 100% de los paquetes.

Y cambiando la configuración de OpenVPN a TCP no he notado el problema pero claro tiene un latencia mucho más alta.

¿Alguien a notado el problema de UDP? ¿Saturación por estos días de VPN, Skype y similar?

Parece que una vez mas es culpa del Router Sagemcom F@st 3686, en casa de mis padres esta en modo puente y un 2º route neutro gestiona todo, pero en mi casa no lo tengo así pues apenas me ha dado problemas aquí, pero al ponerlo en modo puente y directo a un PC, sin problemas

A mi el router Sagemcom me corta las conexiones ssh cuando estan un tiempo inactivas. Tengo que configurar un envio de paquetes cada 60 segundos en el cliente ssh.

A mi eso no me ha pasado, en este caso notaba los tirones por que el ssh va por UDP por estar dentro de OpenVPN

Eso lleva pasando desde el TC7230.

Yo ya he configurado todos los servidores con un keepalive de 240 segundos para evitar eso, porque veo que es cada vez más habitual.

Para un uso normal el Sagemcom fast a mí me va bien con un reseteo de vez en cuando, pero me imagino que a cualquier cosa más avanzada ya me va a tocar modo bridge.

Alucino, he configurado un 2º router algo antiguo de 100 Mb/s con OpenWrt (dejando el de la compañía en modo puente) y ha mejorado hasta el ping a casa de mis padres de unos 70ms a 45ms

Los routers de las operadoras mejor que no hagan de routers. Y si es posible (FTTH), quitarlos de en medio y poner una ONT.

Sabes si mejora el Ping a juegos y demás? Porque si es así lo hago

El ping a los servidores de juegos, solo lo puedes mejorar, si haces un sacrificio de 10 RTX3090 y 5 i9 10900k al dios Pingus en una noche de 31 de Febrero de un año trisiesto mientras le prendes fuego al CPE de tu operador y recitas los textos sagrados. Sobre todo el mantra número 5, ese lo tienes que repetir durante 6 horas seguidas, para que funcione la invocación … "Me importan 10ms, porque yo los valgo, yo los noto, yo los percibo. ¡Oh Pingus! ¡Concedeme la rebaja de 10ms! y te prometo arrasar con los infieles alemanes que están con ADSL y me hacen sufrir Goshting"

No va a hacer nada. Que le haya bajado la latencia tiene mucho más que ver con la red que con el router.

Un router no va a acaparar 25 ms porque si.

¿Que no?, este route hace cosas muy extrañas, ha sido ponerlo en puente y bajar a 45 ms, mucha casualidad, ademas de perdidas de paquetes en UDP antes y ahora 0%

Pruebalo poniéndolo en modo puente y conectando un único PC (con firewall activado)

Pero, el PC directamente al Bridge, o a otro router y de ahí al PC?

te vale prácticamente cualquier router neutro, porque tienes cablerouter, y no tiene mucho misterio

Gracias por la contestación, pido disculpa pq no soy experto en materias , aunque me valgo buscando manuales y puedo instalar las cosillas siguiendo los pasos . Preguntaba por saber alguna marca fiable calidad precio . E imagino q comprar alguno más antiguo tb dar esos 300 o si al ser mas antiguo no soportaría… estoy verde , gracias.
