My first thought when I read the mail was that while it is certainly a
useful tip, I would want to be very clear on the site's security policy
before doing this. If they are tight on security (which they may be if
Internet access is not available), then opening up an unauthorised backdoor
connection to the internal network, and inviting a third party to use it,
could be a seriously career limiting move.
