DHCP is not available (OpenStack router on a stick)
-
This is my setup, problem and shots at fixing it all in one image:
As you can see above, I have a router on a stick setup. It's on some remote datacenter and I'd like to create a stretched-LAN-type of setup, I already did everything with only remaining to turn on DHCP on the firewall so local devices can get their address directly from over there. However, I've set up the static address needed for the DHCP server on all possible interfaces one at a time and in all it fails to recognize the subnet or just can't be configured since it's the tunnel's interface. I've done this a million times, I know it should work--the local firewall is a router on a stick (LACP, but still…)
The only difference I was able to find compared to what I've made work before is that it's on OpenStack, it's a very foreign environment to me, just deploying the image took much more time than I care to admit and it has one of those vtnet interfaces which are always trouble. I've dealt with them before way back. From what I can remember they don't behave like a "full" NIC like other virtual device but more like an SR-IOV virtual function or VLAN of a NIC; a stripped part that can't be divided further, if that makes any sense.
Could that be it? Or am I missing something else?
If a new virtual interface is added on the hypervisor, would it mess with the configured logical ones?
Thanks.
