I'm not sure asterisk is even listening for the packets:

My bad:
netstat -apnu | grep 4569
udp 0 0 0.0.0.0:4569 0.0.0.0:*
3176/asterisk
But why isn't asterisk seeing/acting upon the registration request?
Wireshark finds the packet to 4569, so it's not a firewall problem.
Are you sure about that? I have found in the past that tcpdump sees inbound
packets before they get to the iptables filter.
What happens if you do:
iptables -I INPUT 1 -p udp --dport 4569 -j ACCEPT

Wow! Look:
iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
ACCEPT all -- anywhere anywhere ctstate
RELATED,ESTABLISHED
ACCEPT icmp -- anywhere anywhere
ACCEPT all -- anywhere anywhere
ACCEPT tcp -- anywhere anywhere ctstate
NEW tcp dpt:ssh
REJECT all -- anywhere anywhere
reject-with icmp-host-prohibited
Chain FORWARD (policy ACCEPT)
target prot opt source destination
REJECT all -- anywhere anywhere
reject-with icmp-host-prohibited
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Which means to me that the INPUT chain will ACCEPT all protocols from
anywhere to anywhere.
But no, iptables -I INPUT 1 -p udp --dport 4569 -j ACCEPT solves the
problem and asterisk now registers my device.
Now I have to find a way to make it persistent across reboots.
Thanks,
sean
