Thank you for that explanation. I will continue to troubleshoot this issue.192.168.2.1 is my OPNsense on LAN network. ICX is 192.168.2.2. This line is to tell the ICX the route to find the way to the firewall/router. Not needed in your network for other devices to find the way. You either have setup the default route manually on each device or each device get the default route by DHCP of OPNsense. The ICX need this line it that services running on ICX, like NTP, can find the way to the router.
