Reinstalled 7.920 from ISO and still have problems. If I reboot with IPS enabled, HTTP/S proxy blocks everything and SSL-tunnel is down. Disable/enable of IPS solves the problem.
Updated to 7.921, and now it doesn't help to disable/enable IPS, I have to disable IPS to get HTTP/S proxy and Site-to-site SSL working. Sorry, spoke to soon, it does help to disable/enable IPS, so no improvment from 7.920. It does help to disable IPS, reboot and then enable IPS again.
