@Sebastian-Roth Thanks Sebastian, I’ll try checking source ports and see if there is any consistency. I find it very strange that accessing the FogServer through the mount command fails to make a connection on port 51853 but telnetting from the same Client on that port works. The difference is the source port though. There is no record though of the firewall (Shorewall) on the Host to the FogVM blocking any incoming packets on port 51853. All very strange. Something else I will try is taking the FogVM off the VLAN to make testing easier.
