Matthew Here is the route table for my SSVM.

My 'internal' dns servers are on this subnet so there is no specific route for them The public network is on 172.142.100.0/24 (this is not a production system) and is mapped to eth 2. My 'external' dns servers are 8.8.8.8 & 8.8.4.4 like yours but there is not route as they are accessed via the public gateway of 172.142.100.1 I am not using the storage network, so all secondary storage traffic is mapped to my management nic (eth1) I have added 192.168.0.0/24 to the global setting 'sectorage.allowed.internal.sites' and sec storage is on IP 192.168.0.100, hence these two routes. You might find the global setting 'use.external.dns' useful if you do not have any internal DNS servers Regards Geoff Higginbottom D: +44 20 3603 0542 | S: +44 20 3603 0540 | M: +447968161581 geoff.higginbot...@shapeblue.com -----Original Message----- From: Matthew Midgett [mailto:supp...@trickhosting.biz] Sent: 08 April 2014 16:10 To: users@cloudstack.apache.org Subject: Re: System vm's with wrong network routing Erik that would be fine but this is wrong, this means its going to route over the public address as 0.0.0.0 points to my public gateway. 172.16.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth1 172.16.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth3 On 04/08/2014 11:03 AM, Erik Weber wrote: > If you use the same dns servers for both internal and external it will > add a route over mgmt interface. > > Erik Weber > 8. apr. 2014 16:07 skrev "Matthew Midgett" <supp...@trickhosting.biz> > følgende: > >> I destroyed the VM so it would create a new route.
