Hping3 –udp pfSense no responde
-
Compañeros
me pude colaborar con este error, que se me esta presentando, cuando hago un ping de esta forma hping3 –udp 192.168.17.1 pfSense no responde , pero cuando lo hago a una maquina local si funciona
no tengo rules que bloque esta any-any en la LAN
gracias

No creo que vayas a recibir nada de respuesta, pero puedes verificar con tcpdump en pfsense que si le llegan los paquetes, solo que yo lo he visto de otra manera:
client1:
hping3 –udp -p 10000 --destport 53 192.168.2.4 (IP Pfsense)
Pfsense:

periko
capture esta traza, no se si se este presentando algún problema ya que al parecer no debería ser la respuesta adecuada#hping3 –udp 192.168.200.1
host que hace hping3 >>>192.168.201.6 al pfsense que tiene la IP 192.168.200.1
y no se que es lo que esta pasando
