Well I've just completed the routed setup after seeing the "horrific" effects of the bridging thing on my network. In an attempt to see why upstream speeds are so slow I used Wireshark to sniff the network traffic. The traffic on the NIC to the SMS-200 was clean but on the other interface to the regular network each and every packet was duplicated and/or ACK'ed twice, out of order etc. Since there are no ways (I know of/could find) to configure proper forwarding rules or to fix this in any other way I just gave up on it for now and switched to this routed setup.
To elaborate a bit for those wanting to reproduce:
NIC 1 is the primary and regular interface to my network. It has a fixed IP 192.168.1.1/255.255.255.0 and the default gateway to my Internet router which is also the DNS server.
NIC 2 is the secondary interface to the SMS-200; fixed IP 192.168.2.1/255.255.255.0 and no default gateway.
For this to work you have to enable IP routing (example instructions here: http://keepthetech.com/2016/01/enable-ip...ows10.html) in the Windows machine and install a DHCP server on it. (for example this one which I used and works perfectly: http://www.dhcpserver.de/cms/)
The DHCP server with an active DHCP scope 192.168.2.2 to 254 is active on NIC 2 only and gives out the IP address to the SMS-200 which doesn't support fixed IP's (same goes for the microRendu). It sets the DNS server to the IP adress of my router/DNS server and the default gateway to 192.168.2.1.
Also I've added a static route in my router for the 192.168.2.0 network with the gateway to 192.168.1.1. This allows any machine in my network to connect to the SMS-200.
This setup works perfect with Roon, the SMS-200 is found and I can stream music to it but as expected Shairport/Airplay mode does not work for the reasons I detailed in my previous post.
I'll play with this setup for a while and re-evaluate later, for now I'm done as it's beginning to feel like work!
