I have never heard or seen IKE on tcp 500. But you are right in that my
/etc/services lists that too.

It's an issue that keeps coming back. The network admin vs the end user.
When is the admin right to block VPNs, and when is the user right to
override the admin? When I'm on a local bank network, it seems proper to
block my VPN. But when a country-wide blocking of VPN is taking place,
how legit do I find that (and how do actual local laws interpret any
circumvention of such a block).
