Instructions for Service Providers to enable FrontM application usage on SatCom/MSS/VSAT connected vessels and remote sites.
The FrontM platform uses a number of IP addresses and ports for the range of functions on the platform. Unlike standard distributed cloud architectures that use dynamic IP addresses, FrontM platform has been carefully architected to enable scalability over fixed IP ranges. This means our satellite connectivity partners and installers can easily configure the traffic rules by white-listing FrontM IP addresses.


Traffic White-list

Service providers may choose either Option 1 or Option 2 configurations below. 

Option 1. FQDN White-listing

Where it is possible to white-list Fully Qualified Domain Names (FQDN), all of the below three domains need to be allowed for platform communication and automation functions to work: 


FQDN Protocol Ports
* TCP 443
* TCP 443 TCP 443


Some routers might not be fully compatible with wildcard subdomain whitelisting and not all subdomains would be allowed. If this is the case, please whitelist the following subdomains:

  1. Instead of * Whitelist and
  2. Instead of * Whitelist


Option 2. IP-Address and Ports White-listing


For those who cannot white list FQDN, below are the IP addresses and ports used by FrontM communications platforms to white-list.


IP Addresses Protocol Ports ( ( ( ( ( ( ( ( (Gateways) (Gateways) (Gateways)

TCP 443 (resources) (resources)

TCP 4443 and 443 (video conferencing)

TCP 443 and 5349 (video conferencing)

UDP 10000 and 3478

TCP 443 and 5349

UDP 10000 (PSTN calls)


TCP 5060, 7089 and 8089 (PSTN calls) UDP

5060, 6000 to 20000 (Network transversal Service) TCP

443, 3478, 5349 (Network transversal Service)  UDP



In order to receive push notifications on closed networks, the following IPs and ports need to be opened for INCOMING traffic:

System IP Addresses Ports
5223, 443 and 2197
Google No IP restrictions since Google changes them very often 5228, 5229,5230 and 443


Testing The Configuration

To verify if you have access to FrontM from your network follow the below steps

  1. Launch the below URL from a browser on a computer connected to the network on the remote site:
  2. Click on the “Run all tests” button
