My network admin asked to change the managment ip addresses so now they
are a 172.16.0.0/16 I wiped the database and setup the system again. I
am still having problems resolving dns from inside of ssvm. Its wierd I
can telnet / ssh out to my mail server by using the ip address. The
only thing I can think of is the iptables on my host must be wrong. Can
someone please look at this and tell me what to do.
I do not see cloudbr3 which is connected to my public interface. I'm no
iptables expert so if you can help with the commands to add to this
list it would be very helpful.

Does your management network have internet access? CS routes
internal dns
over mgmt network and if your mgmt network doesnt have internet access
you're basically without dns if you specify the same dns servers (Looks

I am having trouble getting ssvm to connect to the management lan
over the
private ip. Also I can't get it connect to the outside world. I can
ping
the public gateway from ssvm and I can ping the public ip of the
ssvm from
an external address. Something I noticed is that I can't ping
anything on
the management lan from the ssvm.
BTW my primary storage is on fiber so its really not across the
management
lan. My secondary storage is on the management lan.
