Remote Desktop over secure VPN or Gotomypc/Logmein ?


  • GotomyPC:         $20/1 computer/month
  • LogmeIn:            $349.99/2 computers/year
  • VPN:                     Depend on what hardware do you want, for example, I use this Router/Firewall/VPN/WIFI at the low price $149.95  one time upfront cost. for most of my small business, because it has enterprise features with affordable price. It can perform well enough for ten VPN connections at the same time. It is well fit for the small business network.


  • Secure VPN stands for (Virtual Private Network). It acts as if your VPN Client PC in the same network at Work. All the data from the VPN client to the remote network encrypted using vary of protocol, like SSTP, L2TP/OPENVPN, etc.
  • GotomyPC/Logmein/or alike act as a proxy, your client PC communicate with their server through secure hypertext protocol, https, just like your PC browse some secure web site. Their proxy server communicates with your host PC at work using their proprietary protocol. It is why this technology bypasses your company firewall. If you can brown the Internet, you can always logmein/gotomypc unless your company using a proxy for browsing the Internet.

Base on my experience RDP (remote desktop) over secure VPN is faster and secure, and I can remote into any computers at work without paying extra $/computer/month using RDP.

Behind the address bar

Have you wonder how you type in the URL to the address bar browser, and it displays a content of that URL?

Under the hood, the browser using the DNS, domain name system) to resolve the URL’s IP address and make a connecting to that host using protocol HTTP ( port 80) , or https ( port 443). This a fun part, sometimes we spell the URL wrong, the DNS resolve a different IP address which belongs to some bad host, and the browser display you a fake “Your computer infected by Virus”, but actually your computer is 100% virus clean, or a content of fake bank account look like your bank account to steal identity.

This is called “IP phishing”. Just hold the power button long enough to shut down the computer, and restart the computer normally.

How to prevent this problem. Use DNS from, and assign those two IP addresses to your DNS in your main DHCP/Router. This way, OPENDNS have a blacklist of bad IP addresses and warning you to access the site, instead of hand in a bad IP to your browser.
