Firewall DHCP enabled

[Andrii]

For what needed option "DHCP enabled" ?
I can setup any IPs on the VM with DHCP enabled and without.

Hi,

this is for the firewall.
This option allows udp outgoing sport 68 dport 67 and incoming sport 67 dport 68.
So you can use DHCP without make an extra rule.

Do you mean this allow to use DHCP if all other ports are DROPed?

 

[wolfgang]

Yes

Oh man, I wish this was documented in the interface. You know, a little tooltip or a string when you change the option.
I've spent some hours trying to figure out why my VM wasn't getting an IP address ... (well, I'm a noob )

What about Router Advertisment ? The documentation doesn't specify anything about this

FYI: Just found out that this only works for a DHCP client, a DHCP server has the ports reversed and therefore you actually need your own rules.
