<div dir="ltr"><div>Hello Aditya:</div><div><br></div><div>This is not possible in Neutron. If you want to segregate the traffic, what I recommend is to create a network per service and each network with the corresponding subnet. Each external network will be the GW of a router. Any VM that needs to have access to any service (external network) can create an internal network and connect it to the corresponding router.</div><div><br></div><div>Regards.<br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Apr 24, 2023 at 3:17 PM Aditya Sathish <<a href="mailto:saditya@vt.edu">saditya@vt.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hello,<div><br></div><div>We currently have an external network that is being interfaced from the physical interface of the compute server to an L3 switch with different subnets to different services.
