Routing with a PIX?

[jksnook]

Is it possible now with the release of 6.3(4) to route to internal networks with a PIX? I understand that the fundamental rule of a PIX is to recieve on one interface and pass to the next but when will it be possible to use the PIX as a simple internal router as well as gateway?

What the PIX will not do is issue ICMP redirects. If there are two paths out of your subnet the default gateway (router) must be able to redirect hosts to the second (PIX) path.

I have been told the PIX doesn't do ICMP redirects for security reasons but I think this should be added as an optional feature.
