44.0.0.1 doesn't respond to pings from amprnet because of brokeness. It's a bug in the kernel on amprgw which I've never been able to track down.
Ok, that solves that part of the mystery. I'm still curious as to why I cannot get to the webpage however.
I note that your gateway machine is not responding to pings from the Internet on its commercial address.
Well, that's very curious indeed. I just pinged my machine, and it responded just fine for me.
$ ping ampr.k1qv.com PING ampr.k1qv.com (54.214.234.149): 56 data bytes 64 bytes from 54.214.234.149: icmp_seq=0 ttl=42 time=67.445 ms 64 bytes from 54.214.234.149: icmp_seq=1 ttl=42 time=86.558 ms 64 bytes from 54.214.234.149: icmp_seq=2 ttl=42 time=84.399 ms 64 bytes from 54.214.234.149: icmp_seq=3 ttl=42 time=98.167 ms --- ampr.k1qv.com ping statistics --- 4 packets transmitted, 4 packets received, 0.0% packet loss round-trip min/avg/max/stddev = 67.445/84.142/98.167/10.970 ms
Not really sure what's going on here. As I said, I pinged n6mef-gw.ampr.org(44.4.2.153) as a test with tcpdump running. I see the IPIP encapsulated ICMP requests and replies working as they should between my machine and his gateway...
So... we know that I'm receiving IPIP encapsulated traffic from 44.0.0.1 because I'm receiving the RIP traffic, however, tcpdump shows no inbound traffic when trying to ping my 44.4.36.1 address from the internet.
Stupid question here, was I correct in assuming that my net44 subnet was routable from the internet?
