We have updated our Access Server 2.5 beta 1 release to version beta 2, to address a small issue found during testing that would make the Admin UI inaccessible if a specific optional configuration key (vpn.server.cipher) was not defined. This could only occur under very specific circumstances but it has been fixed. We expect to be able to push this release to stable within the next few weeks.
For details we suggest you head on over to the beta release page.
We welcome any feedback, good or bad, and kindly suggest you do so using our support ticket system, and to please notify us that you are testing the beta release, and not the stable release, when you make a report to us. Instructions on how to leave feedback are also mentioned on the beta release page.
