Topic: DHCP on additional LAN IP?  (Read 608 times)

Dear all

Obviously, there's the option to add a second subnet on the LAN interface.
Is there any chance to add DHCP reservations (not a free range) to this second subnet?


DHCP Range
PC-1 aa:bb:cc:dd:ee:ff
PC-2 00:aa:bb:cc:dd:ee

on the SAME subnet/broadcast domain


Printer1 bb:cc:dd:ee:ff:00 192.168.11. 22
AP3: cc:dd:ee:ff:00:11

The issue is that I cannot predict on a certain switchport whether a PC or any other device or a BYO (taking a free range IP) will be connected.

And no, due to other limitations in the network, I cannot make just one /23 or greate subnet. Wink

Any help is appreciated.

Best regards,

You can not have two DHCP servers on the same collision domain.  And there is no way I know of to use DHCP to assign outside of the scope without using DHCP passthrough and some kind of identifier.  And the DHCP in m0n0wall is even more limited.  You may need to get a switch with vlans and do vlan tagging.

Basically the answer I feared to hear.  Grin
