I've got influxdb running on my internal network and it works fine for my
internal clients. But I am unable to get data from my external clients on AWS
EC2. I can see with tcpdump that the packets are being received by the influxdb
server, but the data doesn't load into the database. I do see some "bad udp
cksum" errors in tcpdump. I've tried some suggestions from the internets and I
can't get rid of those errors, and some sources say they may not be an issue.
In the following output 10.0.0.10 is my external client, 192.168.0.211 is my
internal client, 192.168.0.217 is my influxdb server (ip addresses are not
real).
