Run process (shutdown and restart one VPN Tunnel) based on automatic process variable imput

Question

I need to run one shutdown and turn on VPN tunnel based on one external parameter. 
 How I can do this in automatic way? 
 I can reach access to Terminal Firewall interface and I cannot find the CLI available commands to work with it? 
 There is another way to run firewall process in base on external issues? The UTM can provide any kind of Web Service? Or another way to run procedures in the FW? 
 
 Thanks in advance. 
 Gabriel.

Let's assume you have an IPsec connection "Gabriel" that you want to enable. At the command line as root, type in 
 cc ipsec connections exit 
 Let's assume that included in the result is a line 0 'REF_SitGabriel' [Gabriel] . Enable it with 
 cc change_object 'REF_SitGabriel' status 1 
 Similarly, you can disable it with 
 cc change_object 'REF_SitGabriel' status 0 
 Was that your question?

 EDIT: Corrected line to disable - thanks to fellow member teched!
