Our support team received a call from a customer complaining that their next generation firewall (NGFW) was intermittently blocking access to their new voting website. As we were in the process of making firewall changes inside their environment and are responsible for the management of their network they turned to us for help.
The website was a vanity domain hosted at GoDaddy that redirected users to a deep link within another website. We accessed the site and confirmed that it was working properly and sending a 301 redirect as expected, it worked properly both inside their and our environment. We reviewed the firewall logs and found no indications that traffic was blocked by any firewall or IPS. The customer insisted that there was an intermittent problem accessing the website that seemed to affect some users at random.
The Cloud Services Router 1000v (CSR) is one of Cisco's best kept secrets in the routing and security space. The CSR is an incredibly powerful product that's flexible, adaptable and offers almost limitless functionality at a very low price point. In some cases, this router will cost less to license than the ongoing support costs of the traditional router that they could replace. While infrequently positioned in these roles by VARs and account teams the CSR is surprisingly capable. In this blog post, we will review the advantages and limitations of the CSR in our experience using it on the routing and security side of the business although it's also starting to be used for some Unified Communications related roles.
