For me, my most heavily used IP addresses are those associated with MS hosted Exchange, Azure, and Office 365, including OneDrive, Outlook, Sharepoint and Skype.
The list of valid IPs changes monthly, MS has a RSS feed that provides updates. Is there any way of automating the updates, so that the SRX300 works with an updated whitelist, without manual intervention.
I only have the most basic software licence, which appears to do little more than make turning the box on legal. Strange how the datasheet and informational material de-emphasise the fact that the security features they chose to highlight require additional software licences, at comparatively significant cost.
I'm not impressed, I'm particularly not impressed by the POS that is J-Web. Why ship a product that is so bad? On committing a configuration, I get messages warning me that use of the DHCP configuration command is deprecated, and that JDHCP should be used, in their place. Has anybody found the relevant documentation? Because if it exists, it is well buried.
The SRX300 is pretty uninspiring as a switch as well. The list of what it can't do is longer than what it can do, as a switch.
