In preparation for the install, I disabled the DHCP server in my router and connected my MCE core machine to the switch via one of its two interfaces (eth0). eth1 is disabled in the software, enabled in the BIOS. The IP address of my router (and hence my gateway) is 10.11.1.1. When I go through the installation process, I tell MCE about my network (static ip address - 10.11.1.199 - subnet mask 255.255.255.0 - gateway address 10.11.1.1 (my existing gateway) - dns servers as appropriate from Cable modem configuration). MCE then enables eth1 and sets it's IP address to 10.11.1.1 - obviously causing the inability of any network traffic from leaving this machine. This configuration is depicted in the after image.
I do not want to use this box as my firewall for a number of reasons, one of which being that the WRT54G is performing that function quite nicely.
First off, am I correct in thinking this configuration should work? If so, do I need to disable the other ethernet port in the BIOS so the installer doesn't try to enable it and configure it as the gateway I already have?
