I *think* you're saying: other guests CAN ping host ok. (check/post `ip a`)
Check that networking looks ok on CentOS guest. If ok, what's its vmware config?
(In VirtualBox NAT, I can't access my Linux guests unless I add a Bridged interface)
I'm not familiar with vmware, but this web-search (or similar) may help:
vmware guest can't ping host but host can ping guest
