Dear All Experts,
Based on my current setup, where RRAS installed and configured with both NAT and LAN Routing enabled), all the 3 NVMs behind NAT in private internal network of 10.0.0.x able to access internet as well as able to ping VM2 outside NAT in external network of 192.168.137.x. However, VM2 fail to be able to ping any of the 3 NVMs.
Really appreciate an expert advice on how to resolve the issue above. Is it technically achievable to be able to ping internal network behind NAT? (note: Please do not propose other network arrangement. There are reasons why I would only want to stick to the arrangement above)
