WYSE ThinOS Connectivity
Posted on 2014-04-14
Site A has a Citrix array behind a SonicWall router
Site B had the IIS FTP server which fed the INI file to the S10 units
Units outside Site A CANNOT connect to the FTP server or the array consistently. So we moved the WNOS files to Site A to be served locally on a FileZilla FTP server. We are watching connections to the server, however the units are still not consistently getting connected to the FTP or the array.
NOTE: S10 units INSIDE the Site A firewall are working perfectly, every time. There is no rule we see on the firewall that would block FTP or cause intermittent connectivity with VPN traffic (we are allowing "All" to/from the VPN). The only two things that changed in our environment recently are: A few weeks ago we configured LDAP/SSO on our firewalls, so HTTP traffic is being authenticated across the same tunnel. Also, we put a pre-release firmware on the router at Site A to address some other issues. These two changes are the only ones that fit the timeline.
