Compatibility issue with Silverstripe and Firewall
Hi!
My client has installed a hardware solution firewall – NETASQ U250. Since then, he has problems with using Silverstripe CMS.
My first brief investigation indicate:
   No problems on some computers
   On other computers, after logging in and expanding blog-holder in site tree, page doesn't show up
   The revolving icon showing loading of blog entry keeps on animating
   No content is shown.
   Computers have the same rights in firewall
   Both are standard user accounts.
Has anyone come across such incompatibility with firewall (it has been installed in order to limit the websites that can be accessed from clients' network). Should I provide more information on O/S used ?
Kind regards,
Stephen Jackson.
