Ranier,

I verified the link you gave and also checked AWS documentation and found the exact output as shown in AWS:


[ec2-user ~]$ tracepath amazon.com 1?: [LOCALHOST]     pmtu 9001 1:  ip-xxx-xx-xx-1.us-west-1.compute.internal (xxx.xx.xx.x)   0.187ms pmtu 1500

Should the LOCALHOST pmtu needs to be updated to 1500 ?
Or  us-west-1.compute.internal  should be set to 9000.
I think both must match. 9000 are jumbo frames.
The bigger the better.

Try switching to 9000 first and 1500 if it does not work.

regards,
Ranier Vilela
