firewall and ics problems

hello

i had a windows xp network with ics and now i have switched to vista.

my network:
one network adapter is connected to the isp's modem
and one network adapter is connected to the internal network for
sharing the internet connection and the resources of the pc to the
other pcs.

with xp i had no problems with this configuration but in vista i have
many problems.

first of all the windows firewall dont recognize that the internatl
network card (where ics is on) is connected to a network and so the
firewall always thinks its an unknown network.

i havent found a way to tell the firewall that this is my private
network because i use ics - why doesnt the firewall know that when ics
is enabled?

the second problem is, i want to use two firewall profiles - one for
the internet connection and one for the private network.

so file sharing and so on should only be possible on the internal
network card not for the external, but as i read on on the microsoft
homepage vistas firewall can only handle one profile at one time.

BUT WHY???? how should somebody make ics with file sharing and a secure
network when the firewall can only handle one profile at one time?????

hopefully someone can help me with this extremly strange problem.
