Cannot see one device in WAN to WAN connected network
I have 2 ESX hosts, in one I created network 192.168.0.0/24, another 192.168.1.0/24 and connected them between 2 installations of pfsense via IPsec WAN toWAN.
Connection works perfectly, I can ping easily from one network to another.
But I have one problem I do not understand.
In 192.168.0.0/24 network I have device (qnap machine) with address 192.168.0.110. This device is connected to ESX host and ESX virtual switch via NIC and network cable. This device has permament IP.
I can ping it from 192.168.0.0/24 network without any problem. But I cannot ping it and access from 192.168.1.0/24 network and I do not understand why.
Can you please advice?
