17.7 Legacy Series / DHCP Server - Available Range issue

« on: November 06, 2017, 11:03:03 am »

I am trying OPNSense now.

I had set it up on a Linux KVM VM.

The network setup under KVM,
- One subnet with NAT, where my WAN Interface resides.
- Second subnet - isolated, where my LAN interface resides

Obviously, KVM assign x.x.x.1 on the both subnet to the KVM host.

Static IP was assigned to LAN Interface on OPNSense to x.x.x.254

Now the Available range is 192.168.100.255 - 192.168.100.253
Because of the check I will not be able to create any IP pool.

I changed the static IP of the LAN interface on OPNSense to x.x.x.2
Now the Available range is 192.168.100.3 - 192.168.100.1
Because of the check I will not be able to create any IP pool.

How to workaround this.
