I found out that it was no longer possible to run an Online Update for a SuSE Linux server which was setu up behind the Astaro Firewall. Even if I set up a frst rule like any-any-allow which is as good as no firewall at all.
I found out that searching for available ftp servers the SuSE online Update dose something that is interpreted by Astaro as a Port Scan.
Any one who runs into the same problem can solve it by disabling "Port Scan Detection" or better inserting a "PSD Network Exclusion" for the particular server to any.
