Just to start with, its a tad default to diagnose a network problems with limited redacted information, such as the local IP address and default gateway.  I appreciate that in some cases this is prudent, but it does make diagnostics somewhat tricky.

However, with this in mind, this obfuscation would suggest that perhaps some of the Red Hat VM has been configured with some none NAT'ing settings.

So, make sure that the network configuration on the Red Hat VM is setup as NAT and within the same subnet as defined within your Virtual Network Editor.  Ping and Traceroute are useful tools to see how far along the network you are getting.

As an aside, does the NAT setup work for other VMs ?
