SBS 2011 Migration Wizard - Stuck on finding the local network

Hi Experts,

I am in the middle of a SBS 2011 Migration from a Windows Server 2003 Enterprise R2. During the SBS 2011 Migration wizard I am at the point of connecting to the local network. Our current local network is a 192.1.1.X network and DHCP is running from the Server 2003 Enterprise (source server). The error I am getting during setup is:

"You Still have a routable IP address. Check the connection between the network adapter on the server and the LAN port on the router, and make sure that the network connection lights are on"

I am getting link lights and can get onto network from other devices just fine. I did dig up this KB for SBS 2008 but not sure if it applies to SBS 2011:

From the above article, it appears SBS servers can only be on, or networks.

Since I am on a network is that the issue?

Also, is it possible to install the SBS 2011 without the migration wizard (standalone domain) then run the migration wizard with the already created answer file? I am currently stuck at the moment and just looking for some possible solutions.

    Yes, that is an issue, and not just for SBS. 192.1.x.x (or more accurately 192.x.x.x, where x does not equal 168) is a *public* address, which means another machine on the internet may have a letigimate claim to that address and routing will break on your network.

    More info:

    You need to use a private network address behind a NAT device for SBS, and *should* be using this for any internal network...SBS just catches this common misconfiguration and enforces it.

    That's what I was afraid of. I took over the network from someone a few years back and it's always been on 192.1.1.X.

    Im going to try and just put a generic linksys router in front of just the new server and try to "trick" it into passing the migration wizard then get it back on the 192.1.1 network after.
