Cisco has a whitepaper entitled "Enabling Enterprise Multihoming with Cisco IOS NAT" that addresses this. See http://www.cisco.com/en/US/tech/tk648/tk361/technologies_white_paper09186a0080091c8a.shtml as well as RFC2260.
see also <http://sa.vix.com/~vixie/proxynet.pdf>.
There are indeed a few thorny issues with this approach; the largest issue is that all connectivity becomes DNS-dependent and raw IP addresses (from both the inside and outside) become virtually useless. Running servers behind this scheme, while doable, is difficult.
and also much fun to watch, once you get it working. -- Paul Vixie
