Hi there,
I'm wondering if anyone else has run into this/has heard of/(is responsible
for)/knows the reason behind large IP providers limiting ICMP on outbound
connections to the same amounts regardless of the size of the circuit?
Apparently after one of our upstream providers switched to Juniper for
some of their equipment their engineers recommended that they limit ICMP on
all customer facing connections to 5mbps. I understand that preventing DDoS
is important but why A) would they apply the same rule to our OC-48 that
they apply to someone else's T1/DS-3 and B) why is that a requirement for
Juniper gear?
(do people still DDoS with ICMP these days? I see a lot of what looks like
udp.pl and hardly any ICMP attack traffic anymore)
Sorry as usual if i'm off-topic.
-Drew
