Dear,

their are 2 bugs (or thats features?) in the firewall with VM with 
Cloud-Init!

(

a) When in VM -> Cloud-Init -> Network-Interface:  firewall set on

AND

b) VM -> Firewall -> Options -> IP-Filter: set on

)

AND

c) VM -> Firewall -> Options -> Firewall: set off / set on - is equal 
will been ignored for IP-Filter !!!

The 1st is that traffic from outside will been blocked, why the settings 
for cloud-init will not been used for the IP-Filter?!
The 2nd is that IP-Filter will not been ignored, when the Firewall is 
generally off in the options! I understand, the filter is one thing of 
the firewall and when the firewall is off, then all filters must been 
ignored?! Thats from the understanding the same as when firewall switch 
off by the network interface!

Regards

Detlef
