I'm a member of the IT department of Sibur, Llc. We need to use ARIS Express but have troubles with connecting it to Internet via proxy server.

Please, help me finding a couple of answers:
1. Is it possible to set up a Kerberos authentication on the proxy server for ARIS Express?
2. Which external resources should be accessible for ARIS Express to be workable?

Thank you for your answers in advance.

With best wishes,
Renat Tushakov.
