What Ports does the Network Based device report outbound on? Port choice is defaulted to 443 which is an encrypted port or Port 80 which is used for internet. Port 443 (https:) is recommended as it typically bypasses any packet sniffing software and proxy servers. Does the Network Based device require that I open up ports on my firewall? No since the AlarmNet network based device makes the request outbound to the AlarmNet server, there is no requirement to open a port for inbound traffic. 1
