I’m trying to set up a weewx system on a pi3 jessie platform but can’t
quite get the last step.
Lacrosse C84612 weather station —> GW1000U lacrosse-bridge —>
lacrosse-alerts website port 80 works well.
I would like to also provide this same stream to Wunderground (WUG) by any
one of three methods:
1. Use Gateway Advanced Setup (GAS) proxy to weewx host to forward to WUG.
2. Copy and forward packets to weewx host with dd-wrt router iptables.
3. Use a hub with GW1000U and weewx host
When I configure method 1. it simply substitutes the weewx host for the
lacrosse-alerts host in the header, confirmed by both weewx logs and
tcpdump. While Wunderground is happy Lacrosse-Alerts is not.
For method 2. at least it is a true proxy using the weewx host address as
the next hop so that they show up at the weewx interface with the original
source/destinations intact. Unfortunately, I have not been able to
configure the user.interceptor driver to recognize these packets in either
sniff or listen mode.
Method 3 will most probably work but the hub I bought on EBay arrived today
with no 7.5V power adapter and none of my collection will do that so I
don’t know. That’s what I get for a $5.00 purchase (listing stated no
power supply).
Ideally I would like to figure out how to make method 2. work. Either a
change in the dd-wrt iptables edits or the weewx intercepter configuration
entries.

mode = listen
port = 80
address = 192.168.1.20
device_type = lacrosse-bridge
serial = 7FFF7AAA295B94B3
Suggestions for accomplishing this end would be greatly appreciated.
Thank you.
