After dealing with the COVID global pandemic for the past year, it should be no surprise to anyone that working from home can be challenging. These various challenges include distractions, demands, lack of equipment (home wireless was never meant to be loaded the way it is now), and of course: bandwidth challenges.
To some users, the challenge with bandwidth might not be obvious, although it’s safe to say everyone can blame their internet connection for any number of things. According to tests conducted by the website Thrillist.com in May 2020, the average internet bandwidth to residential households in the US is 59.5 Mbps, varying state by state. The highest was Maryland at 84.1 Mbps, with the slowest being Alaska, clocking in at a paltry 20.6 Mbps. The average video conference call consumes 400-500 kb of data though, and if you’re doing HD video at 1.2-1.5 Mbps, throw in latency, issues with the ISP and conferencing service being bogged down by oversubscription, and everyone else in the house streaming something over the internet, bandwidth begins to become a problem quickly.
Consider all of that, then throw in virtual private network (VPN) connections. More specifically, full VPN tunnels, where all traffic is getting sent over the VPN tunnel to the company’s data center, regardless of its final destination. This is where things get really messy.
The problems with split tunneling
Most, if not all organizations have at some point in time chosen to secure their employee’s connectivity to company resources via a VPN. At first, a VPN was a secure connection to access local resources located in the company network: email servers, file shares, local intranets, etc. As ISP connections began to get saturated, directly correlating to more and more internet usage, network architects began to “break out” internet traffic, freeing up
