1- Neither MTU nor TCP MSS is implemented on tunnel : Tunnel adds header and packets get larger which results to packets drop by intermediate router. PMTUD is enabled by default on all devices. When a router drops a packets due to the large size, it sends an ICMP message to the sender. La realización de UDP túnel a través de una conexión SSH Paso a paso Abrir un puerto TCP el puerto de reenvío con su conexión SSH En su máquina local (local), conectarse a la maquina remota (servidor) por SSH con la opción-L para que SSH con el puerto TCP-adelante: On udp connections enable mss-fix on one side of the link.

The address may be a multicast address; in this case, a multicast TTL should be specified, and tunneled packets will be sent with this TTL. In my target server. socat is listening to TCP packets from 2000 port and will transform them to an UDP packet and send them to my service … ouah. socat -U tcp4-listen:2000,reuseaddr,fork UDP:localhost:3000 # the -U will tell to socat to do not try listening on 3000 udp port, we have already our service listening to.

This article introduces the tunnel, how it works, and its architecture. I have had proof-of-concept success with a similar construct as this, but where there is a program which reads the UDP datagrams and turns them into tcp stream with 16-bit length prefixes (i.e.
