Which port(s) should I open in my firewall to allow connection to Talk2M?
Talk2M services are firewall friendly as they use only outbound connections.There are no inbound connections from the Talk2M Servers.
To take advantage of the Talk2M services, your firewall should open only 2 outbound ports: UDP port 1194 and TCP port 443.
Those ports are commonly used and open for secure communications. If you wish to discover more on the addresses and ports used by our VPN servers, please refer to KB-0209-00 - Addresses and ports used by Talk2M.
