multiple ISP, one default gw

[Peter J. Blok]

Hi,

I have two ISP, one gives my a dynamic IP and has the default route thru DHCP. 
The other has a fixed IP and obviously no default route.

I would like to place a webserver behind the fixed IP address, but it is not 
able to answer because there is no route defined to the webclient. The 
default route is somewhere else and the request on port 80 can come from 
anywhere.

On Solaris this works because it learns the route and creates a host route 
back. Can you do this on FreeBSD as well?
