Creating Static Routes for different subnets on the same physical interface

pglover19 · Aug 27, 2016, 3:56 AM

I implemented everything tonight and for the most part everything is working great.. Just got to figure some things out with my VMWare setup.

Ask away been using vmware since server 1 ;) well before esx/esxi/vsphere.. I run my pfsense as vm on esxi host 6u2.. Prob best to open new thread in vm section

After the pfSense static routes changes, now I am having a problem with my Unifi APs connecting to the internet…

The wireless APs are the 192.168.1.0/24 network and I have configured the gateway for each AP to be the RVI (192.168.1.2) on the Juniper switch.

The can ping the IP addresses of each AP from the 192.168.1.0/24 network with no problems..

Unifi AP do not access the internet.. When would they talk to the internet? Is your controller on the internet?

why don't you ssh into them and do a few tests, here is one of mine for example.

You didn't change anything other then directly connect the transit to your pfsense.. You didn't change any routes, you didn't change any nats, etc. You go something else going on with them..

I figured out my wireless problem. I found that the wireless clients were not getting an IP address. Originally pfSense was my DHCP server. After last night changes I removed that capability from pfSense. So I had no DHCP server and that was my problem.

I set up a DHCP pool on the 192.168.1.0/24 network (vlan 1 - home LAN network) on the Juniper switch and wireless is working now..

I just want to confirm my VMware setup. The SAN server on Vlan 20 will be serving up all the ISCSI LUNs for the VMs. In my current setup, I am able to retrieve the LUNs to be used as datastores. I have created my VMs and they all seem be working. However; I don't know what IP addresses and GW to assign to the VMs.

Below are some information that may be helpful. My feeling is that the Hypervisor server is not connected correctly to my LB6M switch or I am not passing the correct vlans to the Hypervisor server.

Well my VMWare setup has just gone south when I rebooted the VMWare host server. All my datastores and VMs are gone. The VMWare host is not connecting to the LUNs on the SAN Server for some reason now…

pglover19 · Aug 28, 2016, 11:30 AM

For some reason now, my VM Host Server on vlan 10 is not seeing my SAN server on vlan 20. This is strange.

pglover19 · Aug 28, 2016, 10:45 PM

Well I got the VMWare host to communicate with my SAN Server again. Had to change the Vlan assignment on my VMkernel port from Vlan 20 to Vlan All.

I still feel that my VMWare setup is not correct.

Any help will be greatly appreciated.

Looks like your problem is in your switching.

If you are sending storage traffic between your VMware and your SAN through your firewall you're pretty much doing it wrong.

If that is shared storage for VMs I probably wouldn't even want it going over the Layer 3 switch. At least not routed.

pglover19 · Aug 29, 2016, 1:04 AM

Just resolved all my VMWare setup issues with the configuration attached.

johnpoz · Aug 29, 2016, 12:26 PM

why would you share your vmkern with your other machines.. When you have nics out the ying yang… Put vmkern on its own nic.. Are those 10ge ports.. you do understand your not using anywhere close to that in any sort of load share right..

pglover19 · Aug 29, 2016, 2:21 PM

So what would be your recommended setup?

Yes.. These are 10ge ports. What is your recommended setup for VMWare?

johnpoz · Aug 29, 2016, 4:18 PM

I wouldn't use vmkern as port groups on a vswitch that there is normal data on. If this is san connection for vm host to talk to it storage that should be on its own be 2 nics for failover or not. But you have ports to play with so no reason to lump everything together like that.

So my initial screenshot of my VMWare setup is how you would set it up?

johnpoz · Aug 29, 2016, 10:11 PM

No you still have your 1st vmkern with another port group, and then why are you tagging your other vmkern for storage? I would just put that on a native untagged vlan Your not routing that through a shared interface so why does it have to be tagged?

And then I don't see the point of 3 physical 10 gig interfaces in such setup.. this is a smb/home/lab setup your clearly never going to come close to using more than 10gig, and why would you need failover? This isn't production so why not leverage the other interfaces for other vswitches for putting other vms on different vlans vs wasting them with failover or loadsharing?

Not sure I understand your comments. Maybe you can provide a drawing so I can visualize your recommendation.

pglover19 · Aug 29, 2016, 11:58 PM

On vSwitch1, for the VMkernel port, I am only using vmnic0. For the Servers Virtual Machine group, I am using vmnic1,4, and 5.

Is this not correct? Please advise.

pglover19 · Aug 30, 2016, 1:26 AM

If I try to separate the ISCSI VMKernel port on it own vswitch with vmnic0 like in the attachment, it will not find the LUNs on the SAN server. I must add four 10gbe nics in order for the VMKernel port to recognize the LUNs on the SAN Server. That is why I have combined the Servers Virtual Machine Port group with the VMKernel port on the same vswitch.

Maybe I need to take a step back and determine whether my SAN Server and Hypervisor Server are connected to the Quanta LB6M physical switch correctly. Then the next thing to look at is the vlan 10 and 20 setup on the Quanta LB6M switch. I have posted high level and more detail diagram already.

Below is the Quanta LB6M switch configuration for the HyperVisor and SAN Server setup. Please help.
