I'm a beginner to networking and as part of some assignments I have a setup of virtual machines that looks like this: In words, I have two pfsense machines, one on the "right" that is connected to NAT on the WAN interface, my Kali machine on the LAN, the interface having the ip 192.168.53.1 as its gateway with the 192.168.53.0/24

I have a zone-based firewall configuration with WAN, LAN, and LOCAL zones (LOCAL being the zone for the router itself). 24 and has a DHCP server on its LAN interface that serves addresses in the 192.168.2.0/24 I am pretty sure that what I want is eth0 in the LAN zone, but I'm not confident and don't want to breach my firewall.

I am trying to setup a disruption between 2 networks one that is coming from the LAN port and one with a different SUBNET from the other (OPT) port. My LAN is not getting blocked from the OPT subnet and it's also able to access the firewall. I am an unexperienced noob so I do not know what I am doing wrong.

I have a network which is a router connected to a switch which has some LAN ports where PCs are conected and 2 APs. I am pretty new to the topic of networking so I hope I can explain the issue properly. I habe created the VLANs 20 and 39 however, when I create the network and asign the VLAN eg. I cannot log into the WLAN anymore.

As was mentioned in this post : The reason for seeing an incomplete ARP is that "An ARP request was sent for that address, but the host with that address is not up and running on the LAN, so there is no reply" So, if a multilayer switch sends an ARP request to a server and gets no reply, ARP will be marked as incomplete in the switch ARP table.
