summary: Prevent communication between hosts
...
Introduction
============
In some environments it is desirable to isolate one or more hosts, and
prevent communication with external, or even other internal domains.
Loading mod\_isolate\_host on a host will prevent all communication with
JIDs outside of the current domain, though it is possible to configure
exceptions.
**Note:** if you just want to prevent communication with external
domains, this is possible without a plugin. See [Prosody: Disabling
s2s](http://prosody.im/doc/s2s#disabling) for more information.
This module was sponsored by [Exa Networks](http://exa-networks.co.uk/).
Configuration
=============
To isolate all hosts by default, add the module to your global
modules\_enabled:
``` {.lua}
modules_enabled = {
...
"isolate_host";
...
}
```
Alternatively you can isolate a single host by putting a
modules\_enabled line under the VirtualHost directive:
``` {.lua}
VirtualHost "example.com"
modules_enabled = { "isolate_host" }
```
After enabling the module, you can add further options to add exceptions
for the isolation:
Option Description
-------------------------- -----------------------------------------------------------------------------------------
isolate\_except\_domains A list of domains to allow communication with.
isolate\_except\_users A list of user JIDs allowed to bypass the isolation and communicate with other domains.
**Note:** Admins of hosts are always allowed to communicate with other
domains
