Application rules in NSX for vSphere allow you to create advanced load balancing rules which may not be possible with the application profile or services natively available on the Edge Services Gateway (ESG). However, the ESG enables you to add your specific application rules to support your load balancing scenario; application rules are built using HA Proxy syntax.

I have been using Gmail since it’s inception when it was still an invite only email service and haven’t looked back. It’s flexibility and speed have made it my personal email account of choice and with Google steadily adding more services to Gmail and their other online collaboration tools it’s always getting better. So I was intrigued when I found out that Google were giving you a way to extend their Google Apps services further with Google App Script. Although it’s primarily aimed towards businesses that are leveraging Google Apps, you can use App Script to automate your own workflows to make your digital life that little bit easier.
Part 1 in a four part series, this post will look at the configuration of DMVPN Phase 1 and the routing implications using OSPF. Although Phase 1 today is considered obsolete, it is still worth reviewing.
Prior to delving into the specifics of DMVPN Phase 1 configuration, let’s start with a underlay network – NBMA (Non-Broadcast Multi-access Network), the underlay can either be the public internet or a MPLS network.

In the first post of this series, DMVPN Phase 1, the DMVPN concept and configuration parameters that were pertinent to the configuration for Phase 1 were explored. Although the parameters are similar to Phase 1 for Phase 2, the actual operation of traffic flows and routing configuration has changed.

Capturing packets on the NSX Edge is relatively simple, the ESG uses similar capture syntax to that of TCPDUMP with a few minor caveats, which I will cover in this post.
When doing a packet capture, the primary thing to do is to identify the interface you want to capture traffic on and then define the traffic capture filter, which will ensure you only capture the packets that your interested in. This will cut down the noise and leave you with a fairly clean packet capture, however there is no reason you can’t just capture everything. Continue reading “NSX-V Edge (ESG) Packet Capture”
This post will describe the process of setting up a site-to-site vpn from the VMware NSX Edge to a Cisco Cloud Services Router (CSR) 1000v, although we are using a virtual Cisco router, the process described below could be used for any remote device. In this post we will be configuring the Edge Services Gateway (ESG) via the vSphere Web Client, however, the method of setting up the VPN could easily be automated via the NSX REST API.

If you have a MAC and you have ever transferred anything to USB, then opened the USB Drive on a Linux/Windows machine, you would have noticed the creation of .DS_Store files along with whatever the contents you placed onto the USB. Continue reading “OSX deleting those pesky DS_Store files”
