# Configuring IP Interfaces

The IP interface of the LAN/WAN ports can be configured by setting the following:

* [IP Address](https://prosbcdocs.telcobridges.com/configuration-parameters-all#parameter-ip-address)
* [Netmask](https://prosbcdocs.telcobridges.com/configuration-parameters-all#parameter-netmask)
* [Gateway](https://prosbcdocs.telcobridges.com/configuration-parameters-all#parameter-gateway)

### To configure a LAN/WAN IP interface
