Homelab Packet Filtering Configuration

Project Overview

Configured both standard and extended ACLs to filter and secure traffic on a simple network topology.

 

Key Tasks and Accomplishments:

Topology Setup & Initial Connectivity Testing

  • Built the lab topology in Packet Tracer and confirmed connectivity between all devices before implementing ACLs.

Standard ACL Configuration

  • Configured a standard ACL to permit traffic from the Staff network and deny traffic from the Plant network.
  • Applied the ACL outbound on the interface connected to the server network and verified correct filtering.

Extended ACL Configuration

  • Configured an extended ACL to:
    • Permit web traffic from the Plant network.
    • Deny all other traffic from the Plant network.
    • Allow all traffic from the Staff network.
  • Applied the ACL on the appropriate outbound interface and validated the results.

Traffic Verification & Testing

  • Verified traffic filtering by:
    • Testing ping responses from both PCs.
    • Ensuring only the Staff PC could ping the server.
    • Confirming successful web server access from both networks while maintaining strict traffic filtering.
