Tagging Firewall rules within NSX

One of the new features that was introduced as part of NSX 6.2 was the ability to tag a particular firewall rule with a text string which would then be sent as part of the syslog message.  This could then allow you to easily search / filer for that rule within vRealize Log Insight or any other logging application.  This can be particular handy if you have multiple tenants and you want to be able to filer rules based on tenants:


I've created two rules, one to allow access to WEB01 and log with Tenant 1 and another to allow access to WEB02 and log with Tenant 2:



Now if I ping both servers to hit the rules, the syslog messages should be sent with the appropriate tags, and then I can check vRealize Log Insight and I should now be able to filter my logs based on those tags:

New Book - VMware vRealize Operations Essentials

Have you ever wanted to understand vRealize Operations?  Well, my colleague and friend Matthew Steiner (Blog | Twitter) has written a book entitled VMware vRealize Operations Essentials which is now available on Amazon and Packet Publishing.

So, why should you buy this book?  If you've ever seen Matt present at a VMUG or had the please of attending a meeting with him you'll very quickly learn that he knows his stuff when it comes to vRealize Operations Manager whether is be policies, super metrics or capacity planning and 3rd party integration.

Secondly Matt is very generously donating all his royalties to the Princes Trust in Scotland.  He is hoping to raise £5,000 in the next 18 months so this is all for a very good cause.

So if you want to improve your knowledge and skills on vRealize Operations and help out a charity then purchase the book.

Cross vCenter Networking and Security with Service Composer - NOT SUPPORTED

With the recent release of NSX 6.2 we now allow for cross vCenter Networking and Security.  This allows the security posture of your virtual machine to follow it when migrating from one vCenter to another.  As per the NSX 6.2 Cross vCener Installation Guide on page 18 service composer isn't actually supported but we can create local policies on each vCenter that populate a security group based on the name of the virtual machine.  When the VM vMotions from one vCenter to another the VM is removed from one security group and populate in the other.

*** NOT SUPPORTED ***

In my environment I have two vCenter servers called NY-VCSA-01 and PA-VCSA-02 with the following compute, management and workloads:


The default Distributed Firewall Policy for both vCenters is to reject:



I'm now going to create a new security group within Service Composer and populate it based on the virtual machine name containing the work "web".  First go into Service Composer and create a new security group:


Give it a name and click Next:


Set the correct matching criteria which in my case is to populate the group if the VM Name contains the word "web" then click Finish:


Ensure the same Security Group is created on both the Primary and Secondary NSX Managers.  Once completed if you have any VM's with the name "web" in the text then they should be members of the security group:


We are now going to create the policy that we will apply to the security group.  The policy will be configured accordingly:

ANY -> Security Group -> HTTP/HTTPS -> Allow
ANY -> Security Group -> SSH -> Allow
ANY -> Security Group -> ICMP Echo / ICMP Echo Reply -> Allow

Go back into Service Composer and create a new policy and give it a name:


Create the firewall rules as required and then click Finish:


Apply the policy to the security group:


Ensure you have identical security groups and policies on both the primary and secondary NSX Managers.  

I currently have WEB01 running in NY-VCSA-01 and WEB02 running in PA-VCSA-01 and I can check what distributed firewall rules are currently being applied:



Now when I vMotion WEB01 from NY-VCSA-01 to PA-VCSA-02 the VM will be removed from the Web Servers security group in NY-VCSA-01 and then populated into the Web Servers security group in PA-VCSA-01.  I've tested this via pinging WEB01 during the migration.  As you can see the VM pings fine and then the connectivity drops.  This happens when the VM is removed from the security group on NY-VCSA-01 and not yet a member of the security group in PA-VCSA-01 so the default deny rule is being applied.  Once the VM is populated in the security group in PA-VCSA-01 the rules apply and connectivity is restored:


As we can see the VM is now in PA-VCSA-01 and the same firewall rules are being applied:


Remember this is NOT SUPPORTED but it just shows that it is possible.

We're Slacking at the North East VMware User Group

Duncan (Twitter) and Alan (Twitter) who are both VMUG Leaders for the North East VMware User Group have setup a Slack account / channel / forum or whatever the correct term is for the North East VMware User Group.  Slack allows people to chat and collaborate in real time and we though it would be a good idea to get the North East VMUG community involved and use it for general chat, announcements and ideas for the future events.  So, if you want to get involved create an account and join us via the URL below:

https://nevmug.slack.com


All the VMUG leaders participate so the more members we get the better community we will have. So, what are you waiting for, sign up and join us.  Just remember to turn off notifications if you install the mobile app, it can get quite busy.
