Hello, I'm kinda new to networking and I'm currently working on a network lab to enhance my understanding of firewall concepts. My setup consists of the following:
Virtual Machines:
- Kali Linux VM (IP: 192.168.10.128)
- Windows VM (IP: 192.168.10.130)
Firewall: Sophos positioned inline between the VMs. Interfaces:
- 192.168.10.127 as PortA LAN connected directly to 192.168.10.128
- 192.168.10.129 as PortC LAN connected directly to 192.168.10.130
- PortB for WLAN (not a part of this lab problem)
Objective: I would like to establish basic communication between the Kali and Windows VMs, routed through the Sophos Firewall. This includes tasks like basic ICMP pings and accessing multiple services to the Windows machine from Kali and vice versa. The general final idea is to collect traffic, and detect malicious payloads through IPS functionality.
Challenge: Despite configuring some initial firewall rules on the Sophos, I am unable to achieve connectivity. I'm uncertain about the potential need for NAT, Port Forwarding, Bridging Interfaces etc, or if other configuration elements are required.
Could someone please provide clear steps on how to properly configure the FW for my scenario? I understand that there were many similar topics however I couldn't solve my objectively simple issue. A link to similar issue or doc would be greatly appreciated.
