Hello,

my next project is to block subsequently unwanted Computers.
The clients in the LAN-Area get the DHCP-IP from my OpnSense Firewall.
At certain intervals I would like to look in the DHCP Logfile or DHCP list, which unwanted Client got an DHCP-IP.
If I see for example an Android-Smartphone, then I want to block subsequently.

Is this realisable ?

Could you please tell me where I have to make the necessary adjustments?

Hello!

Iam a newbie with OpnSense. My Firewall experience was as yet with Ipcop. It is a linux based firewall.

Today I installed OpnSense 16.7-amd64 with two network cards (WAN and LAN).

This is my test environment:
Provider (Fritzbox/Gateway) -------WAN-OpnSense-LAN--------CLIENTS

The IPs are:
Fritzbox  (Gateway)  = 192.168.1.1 (Static)
WAN OpnSense        = 192.168.1.11 (DHCP from Fritzbox)
LAN OpnSense          = 192.168.0.1 (Static)
Clients get IPs from DHCP-range 192.168.0.10 < 192.168.0.250

After this installation, I can go the internet. Perfect!
But if I change the WAN-OpnSense IP from DHCP to static (in 192.168.1.250), then I have no Internet.

I think I must entry the DNS and Gateway IP manually. But I see so many settings and I couldn´t find the settings for this two IPs. I was unsure and I tried something, but it didn´t worked.

Could you tell me please, where I type the rest settings exactly in OpnSense?
