Hello, the company who handles our networking (I just do the server & desktop support) installed a RouterBoard with v 2.9.50. He’s been overwhelmed with new business, so we’re not getting much help from him unfortunately. We seem to have browsing issues with Newegg.com, and more importantly one of our new customers site, www.cbtno.com. With their site, it seems to be having problems loading images and everyone not on our network seems to have no problems navigating around their site. About a year ago, something happened with the web proxy service which caused it to not function, and we were able to browse without any issues at all (of course, we were also able to browse blocked sites too - a bit of a drawback 
). Once the proxy service was restarted, our browsing problems resurfaced. Is this a common thing with 2.9.50? He’s talking about supplying us with a newer RouterBoard with a faster processor so we can move to version 4. Just mainly wanting to see if we’re the only ones having this sort of issue. Thanks in advance!
That version is completely out of support.
Force him to upgrade hardware and software.
