Chris KQ6UP,
I noted the same behavior last month regarding my station connecting to others. You may
wish to read over the January 2013 discussions regarding this.
It was determined that stations were using various Network Operating Systems and that
users assumed services are available that were not.
It was noted that there was difficulty with a JNOS stations reaching my station, this
problem dissappeard when I maintained an open Telnet connection to them.
We came to a concurrence that for testing it's good to have all online 44 IPs respond
to ping. Please note traceroute employs UDP ports 33434-33534, when setting up my
router's firewall, I had to especially make sure I permitted echo-request and UDP
ports 33434-33534 to my AMPR Hosts.
Others note that they perform a Telnet to AMPR Hosts in order to test them; that is not
advisable, as not all AMPR IP hosts are Telnet enabled.
Also, feel free to Ping or Traceroute from the following address:
