Hi, If you are creating isolated network with your /27 cidr and deploying vm in that , default gateway on the vm will always points to ip address configured on the virtual routers guest interface. So for the vms to point to the gateway in /27 cidr, create a shared network and deploy vm in that.

I have one IPv4 /27 for Public IPs and that's working fine. Now what I want to do is assign a live IP address from another /27 to a Guest VM, which appears to work but can't actually touch the default gateway. So here's the rub: The default gateway is actually provided as a virtual IP on two VRRP nodes (for A/B redundancy) by my upstream provider. I can ping the two VRRP routers, I can see the VM has the proper IP address, netmask, and default gateway; and I can configure the VM with a proper IP config which never finds the default gateway IP. The arp cache sees the local MAC address and incomplete for the gateway. So now I'm thinking; according to cloudstack, is the default gateway plumbed on a virtual router? If so, how does THAT route out to the world? I also have a /64 of IPv6 space, /96 of which I have configured in a network offering which has the same upstream infrastructure situation. Same lack of functionality there. So how do I configure my Guest real IP netblocks? Is it okay to be looking for a default gateway IP on a my provider's core router or do I need to have them statically route that netblock to something like the cloudstack management host? Of course I could also have the network offering wrong or incomplete. Any thoughts or pointers to documentation would be appreciated. I can tell I'm making progress because I keep dealing with progressively higher level errors. :) Thanks.
