Fake AP with netmask /16


myn

Recommended Posts

Hi,

I want to activate my lab test FAKE AP, but I have a trouble:

My defaul network and my firewall have subnet 172.16.1.0 with netmask 255.255.0.0

I need to setup fake AP and dhcpd.conf on subnet 172.16.70.0 with netmask 255.255.0.0

but when try to start dhcp I have an error

Someone can help me?

Please...

TIA

Well, obviously. If you place the mask over the IP then both networks end up as 172.16.0.0 so you should either accept that you don't get a /16 or have one of the two use a different subnet.

Easiest is to use 10.1.0.0 / 255.255.0.0 for the one and 10.2.0.0 / 255.255.0.0 for the other.

If you really must stay within 172.16 you can't have both networks as /16 but /15 is possible. For that you should configure things as 172.16.1.0 / 255.255.128.0 for the one and 172.16.129.0 / 255.255.128.0
