Customers with firewall policies in place that are restricted to the node addresses used in Lifesize Cloud, must ensure their firewall rules whitelist all of the IP addresses outlined below. Failure to do so may result in loss of access to the service in the event of a fault or failure condition.

The monitoring and calendaring micro services require communication over TCP port 443 with nucleusproxy.lifesizecloud.com. If you are unable to whitelist the domain, the current IP addresses are 54.68.233.232 and 52.37.153.208.

This complete list of Lifesize Cloud front-end server addresses is always current and available under Advanced Settings on the Lifesize Cloud Admin Console.

Lifesize also announces new server locations and node addresses via the Lifesize Cloud Status Page located at status.lifesizecloud.com. Please subscribe so you’re always in the know.

Hi Michael,

I would like to expand your list of IP addresses to support the Web App firewall traversal methodologies. Web App uses a different method for traversing a firewall than the desktop app does.

In some situations it might be necessary for the Web App to traverse over a single secure port (443 TCP), in these events the call will hand off to a new set of servers / IP addresses to accommodate the traversal method. These IP addresses are listed below.

Cloud Nodes	Tunnel Gateways for Desktop Only	Turn Servers for Web App Only
119.81.134.226	119.81.134.231	119.81.152.130
159.122.100.42	159.122.100.57	158.85.140.178
159.122.152.111	159.122.152.119	158.85.97.148
168.1.68.251	168.1.68.228	159.122.153.194
169.45.75.100	169.45.75.102	159.8.144.180
169.53.184.72	169.53.184.77	159.8.41.131
169.55.87.188	169.55.87.173	168.1.73.132
169.57.7.200	169.57.7.202	169.45.78.148
184.173.213.195	173.192.205.195	169.50.10.10
192.155.215.197	184.173.213.201	169.55.101.52
23.246.195.8	23.246.195.2	169.57.1.68
5.10.105.200	23.246.216.98	192.155.217.58
5.153.63.162	5.10.105.201	50.22.103.178

Hi Robert,

will all traffic of Web App use automatically these gateways via TCP port 443 or are there additional ports/IP's necessary, e.g. Front-End cloud servers for authentication and signaling? What about chat?

I'm also interested in, if this will work in a browser via proxy or do we have to allow traffic to this gateways directly?

Is there a different behavior between IE and Chrome Web App?

Hi Martin,

Today Chrome and IE have a variation on how TCP443 tunneling works. Chrome is the easy one since it natively supports the WebRTC technology, anytime the Web App makes a call it will try to determine the best route for traversing a firewall, the final attempt will be pushing signaling and media over port 443 using TCP.

With the same scenario we found that in some instances the IE11 plug-in is only tunneling the signaling and sending the media directly to the node servers, if the node servers are blocked this will results in a temporary connection for ~60 seconds, black screen, then disconnect. We are in the process of analyzing this behavior and should know more soon.

For the time being, the recommended design is to allow the Node Server and TURN Server IP addresses via 443 if you are running into issues with the IE11 Web App.

Over here you showing 3 columns off IP's for different purposes, in the Cloud admin console where you are pointing at underneath the picture only the Node IP addresses are mentioned, isn't it helpful to show this diagram in total at the admin portal also?

Uunderneath an image how it is shown in the cloud admin console.

Also useful would be to tell where this IP's are located so you can look if there are nodes near by. Is it possible to share the information where the new IP's / Nodes are located?

Hi, I am a little confused. Isn't the cloud web app and the cloud client using the same firewall ports? Just wanted to clarify so that I have a better understanding of how and if these lists of IPs are needed to be added to the firewall. Thanks.

MT, yes the thick client and web app do use the same network ports but if they are blocked they will use different tunneling mechanisms which require separate servers with different IP addresses. If all of the required ports are open the tunnel servers are not needed.

Hello,

We blocked the following ports to force the application to tunneling but it does not work.

- Tcp 35060/35061

- Udp 10000-28000

The bandwidth remains free.

The tunnel will be created over web ports TCP 80/443. Is there a proxy or other device inspecting web traffic? Are you able to log into the client at all?

I have make this post too fast without reviewing.

I think that we succeeded the tunneling but the bandwidth exceeds the 320Kbits which we put on manage.lifesizecloud.com. It is possible?

It would be more easy for our small customer if as in the client Clearsea we had the possibility of restraining the brandwidth in the application.

@Kevin : I don't know for a device inspecting web traffic.

Yes, the client connects.
