[afnog] Routing Issue - Please Help

[Raymond Macharia]

Hi Dewole,just a follow on question, when you say  "the IP subnet is
reachable from the internet", please clarify, for example does it mean you
are able to trace an IP in that subnet from the internet back to your router
(for example from www.traceroute.org)?
