why are walla filtering ICMP?
What does Walla have to do with this anyway?
So if my dest is unreachable, I won't get "Dest unreachable" ICMP?
If TTL epires, I won't know that?
Can anyone check whether traceroute works?
Ping?
ICMPs are part of the IP transport layer to support messages. Why are
they being filtered?
