Description

At boot, I saw the following message:

./ifcfg-eth1:0: line 2: websrv: command not found

It's due to this line:

# cat /etc/sysconfig/network-scripts/ifcfg-eth1:0
DEVICE=eth1:0
*FWOBJECTNAT=host;websrv*
BOOTPROTO=none
IPADDR=192.168.5.223
NETMASK=255.255.255.0

It comes from a NAT 1:1 entry pointing to an host object named websrv.

To reproduce:
1. add an alias ip
2. add a nat 1:1 to the alias
3. recreate ifcfg-eth* files with signal-event interface update
4. service network restart

The value of property FWOBJECTNAT could be only the name of host: FWOBJECTNAT=websrv without host type. The host type can be found in Host database by getting type of key, then the complete firewall object name, useful to get its ip address, can be composed during template-expanding phase. Like below:

# compose firewall obj
$fw_key_obj = $hdb->get($fw_obj);
$fw_key_type = $fw_key_obj->prop('type');
$fw_obj_total = $fw_key_type.";".$fw_obj;

# get hostname
$internal_ip = $fw->getAddress($fw_obj_total);

Tha same approach can be used for /etc/shorewall/rtrules (for MULTI WAN setup)

The format object_type;object_name is a system wide standard and should not be changed.

We can simply change the interface-config-write script to ignore all properties like fwobjectnat.
