Current version: 2.0-BETA2

I configured "Virtual IP" with type "Proxy ARP". If try to change the type of Virtual IP to another (IP Alias), I get an error:
Warning: Illegal offset type in isset or empty in /etc/inc/interfaces.inc on line 812 Warning: Cannot modify header information - headers already sent by (output started at /etc/inc/interfaces.inc:812) in /usr/local/www/firewall_virtual_ip_edit.php on line 221

I think it is saying the error occurred on this line in interface_bring_down:
if (!isset($config['interfaces'][$interface]))
Maybe the caller is giving it bad data, like a blank string for the interface name.

Well, now the error does not occur. But now at change of type virtual IP the previous is not deleted.
I have replaced type from IF alias to ProxyARP and have received at once 2 virtual addresses simultaneously:
# ifconfig em0
em0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> metric 0 mtu 1500

...and if again to change back, are deleted all IP addresses from the interface, except the virtual. Even the main IP:
# ifconfig em0
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

I have tested again.
Now Virtual IP (IfAlias) on the interface correctly is added and deleted.
But at change from ProxyARP to IfAlias, choparp remains running.

Now with one virtual IP really works.
But :)
If to change at once 2 virtual IP (and more)..

- Change from If to ARP.
- IfAliases were deleted before I have pressed the button 'Apply changes'

- IfAliases were deleted before I have pressed the button 'Apply changes'
- Change back from ARP to If.
- Again changes have occurred before button 'Apply changes' pressing. One process 'choparp' was deleted and one remained.

- After button 'Apply changes' pressing, one process 'choparp' still remained, but IfAliases have normally formed.

Some things do change before you apply changes.
1) When deleting a PARP entry, choparp is killed before clicking apply changes (which does nothing). This behavior is the same when changing a PARP entry to another VIP type, it kills it before applying changes (then adds the IP Alias or CARP IP when applying changes).
2) When changing from IP Alias to CARP type, the alias is deleted before applying changes.
Testing the same scenarios as Mike above, I never saw two instances of choparp running (which is the cause of the two issues noted in his last update).

Well the problem with changing the type of alias is that you do not have anymore the information on the previous type.
It would be possible that when resetting a vip alias we try to delete every possible vip type we know, though that might spam logs a bit.
But if you think that is more correct than current behavior than i will try to implement it!
