Firewall Settings 

Pearl Echo's Mobility Monitor  works with a Firewall device through a 

specified group of ports. Pearl Echo workstations establish an initial 

connection with the Pearl Echo Server on a Control Port (Server Port 

Number). Additional command and control communications occur on three 

supplemental IP ports.  The Server Port Number (e.g. 58000) and three 

additional IP ports (e.g. 58001, 58002 and 58003) will need to be opened for 

direct pass thru on your Firewall device. 

Public IP: Server Port Number + 0      Private IP: Server Port Number + 0 

Public IP: Server Port Number + 1      Private IP: Server Port Number + 1 

Public IP: Server Port Number + 2      Private IP: Server Port Number + 2 

Public IP: Server Port Number + 3      Private IP: Server Port Number + 3

Example: 

The Pearl Echo Server Port Number setting is accessed from Network Settings 

in the program's Options Menu.
