Hi All, I'm new to the list and I find it very interesting.
Let me introduce myself: ham since 1996, former call LU8WFY, primary
interests CW, HF and later digital communications. Devoted to linux for
more than ten years. Work in telecommunications since 2001.
Now the problem: I got the assignment 44.153.164.4/30
<http://44.153.164.4/30> from the local coordinator (LU7ABF) and (after
some NAT fighting with my Cisco 877 router) I was able to put it online
from dynamic IP. From the gateway IP 44.153.164.5 there's no problem
pinging to 44/8 and to the outside world. Ping from outside to .5 is
also ok. But when I ping from outside to 44.153.164.6 there's no
response. The strange thing is that, using tcpdump, I see no packets
coming into the gateway from amprgw (of course they do show when the
ping is to .5). Further testing from 44 net (using yo2tm.ampr.org
network tools) showed that from 44 to my host everything works as expected.
I guess that there's some routing problem between outside world and
44 net. I don't know in which way the routes from 44 are propagated to
the rest of the internet.
Maybe I´m missing something but I can't find the problem.
Any help will be appreciated.
Thanks!

Gustavo.
Your both IP's respond to pings from
my server 44.165.2.2
You may try also:
44.165.2.3 (JNOS)
44.166.2.8 (Xnet)
44.165.15.1 (VPN server)
Best regards.

Made typo: 44.166.2.8 instead of 44.165.2.8

Amprgw filters at the per-host (/32) level. Each host which is to receive
traffic from the Internet into AMPRNet must individually be listed in
the permissions file, which is built from the AMPR.ORG DNS 'A' records.
The only host on your subnet which is listed (and therefore is the only
one authorized) is 44.153.164.5. If you want .6 or other hosts on your
subnet to be able to communicate with the Internet, you will need to
have your local coordinator add them to the DNS for you. Or I can do it.
