(You asked a network connectivity question without providing a description 
of the network.  Two demerits.)

Watch out for VIPAs.  Using NETSTAT command or CHKIPADR exit, discover the 
IP address of z/OS during a successful FTP.  Is that the same IP you use 
when originating from VM?

If you suspect a routing problem, use traceroute on both z/OS and z/VM 
(TRACERTE) to see what's happening.
