Solution #00005058
 
Scope:
This solution replies to:
- NG Firewall firmware versions 4.2.x, 5.0.x, 5.2.x
- netfence firmware versions 4.2.x

 
Symptoms:
The control daemon encounters problems deleting IP addresses (e.g. the server ip does not release after a server switch, which encounters a "duplicate IP"). Servers cannot be started although the configuration apparently is correct. You are noticing malfunctions regarding the network configuration on your Barracuda NG Firewall system, which cannot be precisely defined. The server-label column in "Control" > "Network" displays "[]" at the server name or the server name is not displayed completely.
Further the Control has the problem to release Server IPs, if the Server goes down or were blocked. Duplicate IPs can be appear.

 
Solution:

Netfence systems use labels to identify and control the different network devices.
The label of a network device is put together by device name, VLAN-ID and server name, separated from one another by punctuation marks. The label construct looks alike the following:

devicename.vlanid:servername (e.g. eth0.99:foo ). A label, including punctuation marks, must not be longer than 15 characters.


Shorten the server name (use the "copy" or "move" feature, if you use a mc) or the change the VLAN-ID to a shorter value.
