No. They are _IP_ protocols. TCP is an IP protocol (6) as is UDP (17). In
fact, go here: http://www.isi.edu/in-notes/iana/assignments/protocol-numbers
and go nuts.

To do IPSec you need an IPSec image, which I know existed in 11.3 somewhere
as well as 12.x.
To clarify, though, it doesn't sound like you need to run IPSec on your
router - just _through_ it. This should not require any special IOS version.

No worries.
