Router

Is there a write up on the config of the system router.

 

Mine doesn't seem to be handing out DHCP addresses

to my VM's.

The router is commented out.

I chose default isolated network with source NAT service
for the network offering.

The following two lines appear to be commented out.

#dhcp-option=option:router,1.2.3.4
#dhcp-option=3,1.2.3.4

And I can't seem to edit the dnsmasq.conf file.

Check that your /etc/dnsmasq.conf on router is configured to service on the
right subnet. You should see something like the following in your
configuration file.
dhcp-range=<GuestSubnet GateWay>,static

dhcp-option=option:router, <GuestSubnet GateWay>
 dhcp-option=6,10.147.40.75,10.103.128.16
dhcp-optsfile=/etc/dhcpopts.txt

dhcp-hostsfile=/etc/dhcphosts.txt

Is your network offering selected Router as DHCP provider ?

If your network offering contains router as DHCP provider and VM are not
getting dhcp IP then there is an issue.
Also check the ip entry for the VM in /etc/dhcphosts.txt

If everything mentioned below is fine and still not working then try /etc/init.d/dnsmasq restart.

It is in the right subnet.

How do you know if your network offering selected Router
as DHCP provider?

The ip entry for my VM's are not in dhcphosts.txt.

Once I got the VM and Router on the same 
Hypervisor, my VM got an IP. 

However, the router still can't ping the guest/public
LAN and vice versa.  Do I have to set up a  firewall 
rule to get this working?

Warren,

If you're using advanced networking and have multiple hosts, you may want to
check the VLAN trunking between hosts is working for your guest networks.  A
simple test would be to move the guest instance to the same host as the
virtual router and see if it gets it's DHCP address then.
