cat5 cable plugged in, light lit, layer 1. switch has MAC address in its tables, layer 2. routing setup properly, layer 3.
packet exchanged, layer 4.
session created, layer 5.
vpn tunnel decrypted, layer 6.
results displayed in sqlplus, layer 7.

start with the lowest layer and work your way up, never the reverse. ping won't always work, as lots of places block all ICMP.
