How to set up and install a Public IP with a clients own Router or Firewall


For a customer to be able to manage their own network they would need to supply their own router or firewall, which they will configure. We strongly recommend that the client uses internal or 3rd party IT for this process.

A Public IP is needed for each device that requires a separate public address. This firewall/router will be configured with a public IP address which is ordered through Connect, and is then displayed on their Service Guide.

Configuring Services in Connect

The client may require one usable Public IP address or if they have several devices the might need five usable Public IP addresses, be aware that you can only have either 1 x Public IP or 5 x Public IPs per client these services cannot be mixed due to the network setup.

Once the client becomes active on Connect you need to assign the switch port with the role of Public IP.

Connecting the Devices...

The WAN side (Wide Area Network) of their configured router/firewall will need to connect to the Public IP port on the switch.

However, if the client would like to connect their computers to the back of the phones, you need to assign a LAN Only port on the Connect Switches page, and connect this port to the LAN side (Local Area Network) of the router. All other ports are then configured for ‘Voice, LAN, Internet’ as per usual.

essensys recommend that the client manage their own DHCP, you can disable the DHCP on their VLAN from the Network Info page on Connect. From the Clients menu, highlight the specific Client, click the More drop down menu and select Network Info. In here you are able to disable the DHCP provided by essensys so the Client is able to manage their own. (More information can be found on DHCP here).

The above shows how a client with a Public IP should be set up if a client is using the centre's LAN network (WiFi Secure, Switch ports)


If the client has their own switch, they would connect this to the LAN side of their configured router/firewall. All floor ports in the office would then connect to the client’s switch.

The above shows how a client with a Public IP should be set up if a client is using their own devices for their network (their own switch, WiFi, phones etc.)

TIP!
It’s a good idea to test the client’s public IP address and network, before they connect their router/firewall to the switches. Details of how to do so are found here - Testing a Public IP Address in Connect

If the client's router has wifi capability, this should be disabled in order to reduce the possibility of interference in the building.
