Dear list:
I am trying to answer the following question:

Do IP packets (say a series of ping packets),
after the TLS record protocol does it's thing,
become encapsulated in other IP packets bearing the source IP of the
tunnel and destination IP of the opposite tunnel endpoint?

OpenVPN does not make any diffrence on what type of IP packets you send, ICMP, TCP, UDP and so on. So if you ping something on the remote end of your OpenVPN tunnel, then yes, your ping packets will get encrypted and encapsulated within OpenVPN's IP packets.

Note that OpenVPN just gives you an "virual ethernet adapter", so you must setup routing so the traffic you want encrypted is routed through this tun/tap device.

Traffic not routed to this adapter is not encrypted or encapsulated.
