Server IP address and network firewall settings
Your server can have a public IP address (accessible over the Internet) and/or a private IP address (accessible within a private network; for example, via WiFi within a company network). If a mobile client device tries to connect via the Internet using the server's private IP address, then the connection will not work. This is because the private IP address is not known on the Internet and cannot be resolved. If a client device uses a private IP address, then the client device must already have access to the private network.
To ensure that the server can be accessed, do one of the following:
You must also ensure that the firewall is configured to allow access to the server port used for MobileTogether Client communication. The ports used by MobileTogether Server are specified in the Settings page of the the Web UI of MobileTogether Server (see the MobileTogether Server user manual). On the client device, this is the port that must be specified as the server port to access.
Tip: Port 80 is usually open on most firewalls by default. So, if you are having difficulties with firewall settings and if port 80 is not already bound to some other service, you could specify port 80 as the MobileTogether Server port for client communication.
