I have a case in a network that is connected to a VPN s2s, the deployment is : IP a connect to IP c as active - (over vpn s2s) IP b connect to IP c as backup - (over vpn s2s) where what we want is when IP a fails to connect to the internet the s2s VPN connection from IP a to IP c breaks, then we make the script below, which is run on crontab/cronjob on unix every 1 minute: if ping -I WAN -c 3 8.8.8.8 &> 0 then clish -c "set static-route 3 disabled true" else clish -c "vpn tu del x.x.x.x" clish -c "vpn tu del x.x.x.x" clish -c "vpn tu del x.x.x.x" clish -c "set static-route 3 disabled false" fi The weakness of this script is that if the condition fails it will do an else which will repeat itself. which makes every 1 minute run clish -c "vpn tu del x.x.x.x", now what we want is clish -c "vpn tu del x.x.x.x" done only once as long as IP a fails to connect to the internet or 8.8.8.8 explanation: if ping -I WAN -c 3 8.8.8.8 &> 0 -> to check whether ip a can still connect to the internet if successfully connected do this -> clish -c "set static-route 3 disabled true" if failed to connect do this -> else clish -c "vpn tu del x.x.x.x" clish -c "vpn tu del x.x.x.x" clish -c "vpn tu del x.x.x.x" clish -c "set static-route 3 disabled false"

I can help you! Does this script need to be in shell script? Anyway, we can make the necessary changes for this project to work perfectly. I have been programming in Shell Scripts for over 10 years, whether performing complex functions for system administration or simple scripts for initialization of programs.
