Hi Lennart, 

graylog2-web-interface.conf:

# graylog2-server REST URIs (one or more, comma separated) For example: 
"http://127.0.0.1:12900/,http://127.0.0.1:12910/";
graylog2-server.uris="http://127.0.0.1:12900/";

# Secret key
# ~~~~~
# The secret key is used to secure cryptographics functions. Set this to a 
long and randomly generated string.
# If you deploy your application to several instances be sure to use the 
same key!
# Generate for example with: pwgen -s 96
application.secret="OMITTED"

# Web interface timezone
# Graylog2 stores all timestamps in UTC. To properly display times, set the 
default timezone of the interface.
# If you leave this out, Graylog2 will pick your system default as the 
timezone. Usually you will want to configure it explicitly.
# timezone="Europe/Berlin"

graylog2.conf ( I've removed comments and commented out settings that I 
didn't touch ):

is_master = true
node_id_file = /etc/graylog2-server-node-id
password_secret = OMITTED
root_password_sha2 = OMITTED
plugin_dir = plugin
rest_listen_uri = http://127.0.0.1:12900/
elasticsearch_max_docs_per_index = 20000000
elasticsearch_max_number_of_indices = 20
retention_strategy = delete
elasticsearch_shards = 4
elasticsearch_replicas = 0
elasticsearch_index_prefix = graylog2
elasticsearch_analyzer = standard
output_batch_size = 5000
processbuffer_processors = 5
outputbuffer_processors = 5
processor_wait_strategy = blocking
ring_size = 1024
mongodb_useauth = false
mongodb_host = 127.0.0.1
mongodb_database = graylog2
mongodb_port = 27017
mongodb_max_connections = 100
mongodb_threads_allowed_to_block_multiplier = 5

I've not tried specifically setting the rest_transport_uri as the comments 
before it lead me to believe it'll default to the first non-loopback 
address. I've confirmed that the rest API is responding by curling the 
non-loopback address based on the api documented here: 
http://docs.graylog2.apiary.io/

ex:

curl http://10.0.2.15:12900/count/total
{"events":0}

Although interestingly "curl http://10.0.2.15:12900/cluster/nodes"; doesn't 
return anything. Not sure if it's supposed to before I actually configure 
an input or not. 

Thanks,
Joe
