Graylog 3.0 on two networks

Graylog Central (peer support)

Hello everyone,
I have configured on my server two interfaces eth0 and eth1, I want to configure graylog 3.0 to accept connection in both, is it possible?

Yup, just bind the inputs to 0.0.0.0 which will bind them to all IP addresses.

Sorry, I expressed myself wrong, I’m referring to the website.
When I put an entry /etc/graylog/server/server.conf http_bind_address = 0.0.0.0:9000 I can not access the webpage on any of the networks.
Is this possible?

You should read: http://docs.graylog.org/en/3.0/pages/configuration/server.conf.html#web-rest-api

The docs explains the behaviour that is taken by default. Have the Interface available on two interfaces is possible with one of the following:

  • have a DNS Entry that returns the matching network addres.
  • have a proxy that listens on all devices and set the X-Graylog-server header according to network the request is comming from.

I create this entry in my correct dns, how should I leave the entry in server.conf for the two networks, 10.1.1.0/24 192.168.0.0/24?

If you had read the documentation you might have come to the same conclusion. This should work

http_bind_address = 0.0.0.0:9000
http_external_uri = http://your-configured-dns-entry
