This will be part of our testing. The upstream router should still have an on-link route on the network to the floating ip subnet. IOW, you shouldn't replace the floating ip subnet with the private fg subnet on the upstream router. You should add the new subnet to the already existing ones and the router should have an additional IP address on the new subnet to be used as the gateway address for north-bound traffic.</div><span class="HOEnZb"><font color="#888888"><div><br></div><div>Carl</div></font></span></div></div></div>
