Vista Ultimate 32 SP1: problem w/unidentified network + ICS

Vista machine is:
AMD X2 4000 - 3 GB RAM - Asrock AliveNF6G-VSTA Nvidia based chipset - 2 x
320GB SATA2 in RAID0 - dual NIC.

Network connection is
cablemodem <-> Vista NIC1 <-> ICS <-> Vista NIC2 <-> 10/100 switch <-> rest
of my home network which is composed of 4 more machines (3 XP SP3 and 1 Vista
Ultimate 32 T61 laptop). There is a Trendnet TEW-611BRP wireless router
connected to my Ethernet switch which is providing 802.11 Super G to the rest
of the house. I am not using the wifi router as gateway to the internet
because a lightning screwed up the WAN port. It is only an Ethernet to 802.11
bridge.

I have the same problem many people are having: unidentified network which
goes back to Public mode after rebooting the machine. Another problem I have
is that if I turn on network discovery, it will open the RPC port on the
firewall´s WAN connection.

I can share files locally by explicitly doing \\machinename\sharename, but
the network workgroup is not browseable.

I have also added the LLTD client on the XP machines so I could see the
network map. Nice feature, it works really well.

I need help getting rid of the Unidentified network so I can:
- avoid having to reset it to private mode after each reboot
- rename it to something like "LAN". I renamed the public adapter as WAN to
make it easier to remember what cable goes where if I have to reconnect.

I have disabled IPv6 by adding a DWORD DisabledComponents=0xFF in the
registry entry for the tcpip service. This got rid of all the tunnel adapters
and the tuxedo device. I don't like binding extra protocols to the internet
NIC. It´s just a matter of time until someone finds an exploit in MS's IPV6
stack or Tuxedo and the machine is compromised. I am sticking to IPv4 only,
my ISP only supports it, and the extra IPv6 Tuxedo would be useful for
uTorrent but I prefer to play it safe for the time being.

I used to have Fedora 8 installed on this machine and it worked fine 24x7.
No problems at all. Vista is just so full of wizards and automatic stuff that
it is frustrating for advanced users. I appreciate the help from the wizard
but sometimes it is just frustrating.

Using ICS on Vista is just temporary. I will eventually keep this Vista
machine as desktop only and install Fedora or Centos on an older PC and use
that as home server/gateway/router/firewall/backup, but in the meantime I
just can´t have the Unidentified network going back to public mode after each
reboot because it ruins the firewall settings.

Can't I just disable this automatic network location manager and configure
the firewall myself?

BTW, how do I set up port forwarding with ICS?

Here´s my ipconfig:
