This is a tricky issue. First of all I must assume you are referring to
the actions taken by the various checks. These are in fact regulated by
the individual plugins so there is not a single way to solve this.

Example:
If my dns plugin calls dig to do the job then how do I run dig in the
manner you describe? And will such a soulution work for other plugins?

In general I think nagios expects your host to solve these issues. In your
case you could considere working around the issue with NAT rules in the
IP stack of your OS.
