Hello,
Does anyone has reachability issues with AS8388?
It seems i'm unable to get packets back from 194.63.246.0/23, but only if the source is my 193.136.0.0/15 block, at AS1930. It works well from my other netblocks. I'm basically performing a (non-recursive) DNS query to DNS servers within 194.63.246.0/23.
I've been trying to involve upstream providers to take a deeper look at this problem, but i haven't had any luck so far. I can't even get a traceroute back to my network from anyone at AS8388.
Any suggestions?
Best Regards,
Carlos Fria�as
Can you provide the traceroute?

Hello,
Can you provide the traceroute?
Yes. Please see below. We were already told they drop icmp packets making the traceroute useless beyond 62.38.94.98
I strongly suspect there is an issue only on the return path, but i would need a traceroute originated at the other end so i can be sure and understand where the packets (tcp & udp) are exactly being dropped.
