My WAN port address is 10.100.11.130
My LAN network is 192.168.12.1/24
I have a LAN port device with a static IP of 192.168.12.25
I created a Virtual IP of 10.100.11.131
At this point I can ping 10.100.11.130 and 10.100.11.131
If I NAT 10.100.11.131 to 192.168.12.25, ICMP stops working to 10.100.11.131
I can still ping 10.100.11.130
The device with 192.168.12.25 can ping out to 10.100.11.1 (external gateway), 8.8.8.8 and google.com
I can VNC from the 10.100.11.1 network to 10.100.11.131 which NATs to 192.168.12.25 device

What am I missing in the rules to get ICMP working again to 10.100.11.131?
I've tried creating rules to specifically allow ICMP to 10.100.11.131 with no success.
