Erik, I just noticed this in the Citrix CloudPlatform 4.3.0.2 release notes ( http://support.citrix.com/servlet/KbServlet/download/38098-102-713723/CitrixCloudPlatform4.3.0.2ReleaseNotes.pdf), but i can't find this issue in JIRA:
CS-24473 Problem: Restarting VR on an isolate network with egress policy set to allow does not honor the default rule. Root cause: After VR reboot in a network with no egress rule created, the IPtables rules are not created to allow egress traffic. Solution: After VR reboot, rules are configured on VR to add egress default rules to allow traffic -Jan-Arve
