How to change allowed IPs for zammad-railsserver and zammad-websocket

[eavenhuang]

Dear Experts,

In our environment, we have another Nginx server working as our reverse proxy. We need to change the IP parameters on Zammad server, from 127.0.0.1 to 0.0.0.0 for zammad-railsserver and zammad-websocket services. May I know where I can change the listen ports accordingly?

upstream zammad-railsserver {
server 127.0.0.1:3000;
}

upstream zammad-websocket {
server 127.0.0.1:6042;
}

Assuming that you’re ensuring that you know what you’re doing and secure the ports accordingly, have a look in the documentation:

Thanks, we ended up with the current Zammad without another Nginx server as first-layer Reverse Proxy.
