# Basic Usage of Networking
|
||
|
|
|
||
|
|
Vagrant offers multiple options for how you are able to connect your
|
||
|
|
guest machines to the network, but there is a standard usage pattern as
|
||
|
|
well as some points common to all network configurations that
|
||
|
|
are important to know.
|
||
|
|
|
||
|
|
## Configuration
|
||
|
|
|
||
|
|
All networks are configured within your [Vagrantfile](/v2/vagrantfile/index.html)
|
||
|
|
using the `config.vm.network` method call. For example, the Vagrantfile
|
||
|
|
below defines some port forwarding:
|
||
|
|
|
||
|
|
```ruby
|
||
|
|
Vagrant.configure("2") do |config|
|
||
|
|
# other config here
|
||
|
|
|
||
|
|
config.vm.network :forwarded_port, guest: 80, host: 8080
|
||
|
|
end
|
||
|
|
```
|
||
|
|
|
||
|
|
Every network type has an identifier such as `:forwarded_port` in the above
|
||
|
|
example. Following this is a set of configuration arguments that can differ
|
||
|
|
for each network type. In the case of forwarded ports, two numeric arguments
|
||
|
|
are expected: the port on the guest followed by the port on the host that
|
||
|
|
the guest port can be accessed by.
|
||
|
|
|
||
|
|
## Multiple Networks
|
||
|
|
|
||
|
|
Multiple networks can be defined by having multiple `config.vm.network`
|
||
|
|
calls within the Vagrantfile. The exact meaning of this can differ for
|
||
|
|
each [provider](/v2/providers/index.html), but in general the order specifies
|
||
|
|
the order in which the networks are enabled.
|
||
|
|
|
||
|
|
## Enabling Networks
|
||
|
|
|
||
|
|
Networks are automatically configured and enabled after they've been defined
|
||
|
|
in the Vagrantfile as part of the `vagrant up` or `vagrant reload` process.
