General Discussion / DHCP reserved still assigne to other deivce?

« on: October 04, 2023, 03:00:41 pm »

Hi,

I've encountered an issue where I had reserved an IP address for a specific device. However, when that reserved IP is inactive, it's being assigned to another device. I was under the impression that DHCP shouldn't allocate reserved IP addresses. Can you assist with this?IS this a bug?, i remember it never happen in Windows DHCP server

General Discussion / How the firewall rule work?

« on: September 24, 2023, 05:17:58 am »

I am having difficulty understanding the logic of OPNSense firewall rules. Based on my experience with FortiGate, I configured the following rules in OPNSense, but they are not working as expected in OPNSense. I need help from an expert to troubleshoot the issue.

My requirements are:
1.Allow a specific IP address range to access the internet
2.Block a specific IP address from accessing the specific network devices

My OPNSense firewall rule configuration:

**Rule 1**
Interface: LAN
Direction: In
Source: Private IP scope alias
Destination: WAN
Source to destination port: Any
Action: Allow

**Rule 2**
Interface: LAN
Direction: In
Source: Host IP address
Destination: Network Devices IP address Alias
Source to destination port: Any
Action: Block
