Fedora VM networks stalls

[ProPAAS DBA]

Hi all;


I've setup a Fedora 25 VM in vmware Workstation sitting in a CentOS 7 
host behind an untangle firewall.  After running for what seems like a 
few hours the VM becomes unreachable via the port forward rules, I get 
"Connection timed out" while my other VM's (CentOS 6 & CentOS 7) remain

accessible. I've disabled firewalld and enabled sshd on the Fedora 25 VM,


Any thoughts on what might be causing this?


Thanks in advance
