So, we are in the process of moving the primary nameserver away from the UCSD gateway server so all it will be left with is acting as the IPIP encap/de-encap gateway function + rip44d, so don’t rely on doing zone transfers from that server for much longer.

As to your egress problem, I checked on the gateway and your 44.60.44.128 IP is not in the filter list but your 44.60.44.1 IP is, that’s why it’s not working for 44.60.44.128. What is the A record hostname for that IP supposed to be? I can check if it’s in the zonefile or not - likely not - was it added only recently?

Chris,


I suspect some failure in the location that maintains what AMPR IPs have DNS entries - hence allowing FORWARD on AMPRGW.

Rationale:


* My ingress TCP traces are blocked for 44.60.44.128, yet work for 44.60.44.1, 44.60.44.3 and 44.60.44.10


- On a side note, I also observe that on my DNS server (44.60.44.3) - that the 44.in-addr.arpa Zone seems to be failing (checking logs). I can no longer get authoritative answers, but I can still query 44.0.0.1 and get Zone Transfers (port 53/TCP) for AMPR.ORG. Was the Reverse Zone edited somehow?

Chris,


Another interesting observation occurred when testing egress from my LAN and router with various SRC IPs. My LAN is configured with a SNAT and IP/Rules to use 44.60.44.128 for traffic from a certain LAN SRC IP is set on the client.


* With my usual SNAT setting of SRC 44.60.44.128 - ping DOESN'T WORK
* When pining from the router with 44.60.44.1 and changing the LAN SNAT rule to also use SRC 44.60.44.1 - ping WORKS


root@OpenWrt:~# ping -c 5 1.1.1.1 -I 44.60.44.1
