We have followed the ports that Cloudstack requires and opened them in our hosts however with UFW enabled the systemvms agent disconnects.
We allowed all traffic to and from the management host and opened these ufw allow proto tcp from any to any port 22 $ ufw allow proto tcp from any to any port 1798 $ ufw allow proto tcp from any to any port 16509 $ ufw allow proto tcp from any to any port 16514 $ ufw allow proto tcp from any to any port 5900:6100 $ ufw allow proto tcp from any to any port 49152:49216 What exactly is causing the systemvms to disconnect when UFW is enabled ? The moment we disable it and reboot the systemvms the agents come back online Regards, Ben McGuire Founder AeroNeave Cloud Solutions
