I've downloaded and installed UTM 9. Very impressive. I am a startup, micro business owner and was looking to startup with the Essentials Edition and hoepfully move up to a licensed copy as business grew. I'm a bit disappointed. Some of the very first services a small business needs is a web server and an SMTP server. I quickly discovered that the "free" edition will not allow you to provide access to either behind the "basic" licensing version of the product. After having been in IT for over 22 years, I won't buy anything I can't try first. I may just have to move on to another option. Shame really, it looks good through the grayed out, crippled feature set. I'd have thought if you wanted to demonstrate its capabilities you would have at least offered a full working version with limited use licensing.
Good luck!
