[44net] Test Script for ipip Gateway

To the List, I have my ipip gateway set up and working. I can get to a lot of hosts/networks. However, I am not sure I have it set up completely right. Is there a test script that I can run to test out its functionality? Or, even a list of hosts/networks known to be reachable via a properly operating ipip gateway? There's a lot of destinations that I can not reach. Unfortunately, I can't tell if an individual destination is unreachable or simple off the air. A known-hosts list will tell me a lot. If anyone wants to test my incoming access, you can try n2mh.ampr.org or http://n2mh-web.ampr.org. Please let me know the results. Thanks and 73, Mark, N2MH
