I have a a setup with one CAM, one CAS and a firewall between them. There is also NAT in place.
I changed the requiered things like in the configuration guide.
After the changes, I'm able to connect the CAM with the CAS. But after the a reboot of the CAS the connection is broken and cannot be "repaired" because the CAM tries to connect to the original IP and not to the NAT IP which it was connected to earlier. I can only "repair" the connection when I delete the CAS on the CAM an reinitiate the connection.
