Project Report

Site-to-Site IPsec VPN

A secure encrypted tunnel built between two remote networks over a simulated public WAN, demonstrating a full IKE/IPsec negotiation from policy to verified traffic:

ISAKMP Phase 1 (AES, SHA)
IPsec Phase 2 encryption
ACL for interesting traffic
Crypto maps between routers
Verified secure tunnel establishment

Cisco Packet Tracer

NAT Implementation Lab

A focused lab simulating real-world internet connectivity, exploring the full spectrum of NAT translation techniques used to bridge private and public address spaces:

Static NAT for internal servers
Dynamic NAT for multiple users
PAT (Overload) configuration
ACLs for traffic control
NAT translation table verification

Cisco Packet Tracer

GRE Tunnel VPN

A GRE tunnel configured to carry dynamic routing protocols transparently between sites, enabling routing adjacencies to form across an otherwise unaware transport network:

GRE tunnel interfaces configuration
Tunnel source & destination IP setup
OSPF over GRE tunnel
End-to-end connectivity between LANs
Reachability testing with ping/traceroute

Cisco Packet Tracer

IPv6 Routing with EIGRP

A next-generation addressing lab migrating an enterprise topology to IPv6, with EIGRP handling dynamic route exchange across the new address space:

IPv6 unicast routing enabled
EIGRP for IPv6 (AS 10)
Global Unicast & Link-Local addressing
Neighbor relationship establishment
Routing convergence verification

Cisco Packet Tracer

VoIP Network Implementation

A converged voice and data network built around Cisco Call Manager Express, with dedicated voice VLANs and SIP integration for end-to-end call signaling:

IP Phones via SCCP protocol
CME on Cisco router
Separate VLANs for Voice & Data
DHCP with Option 150
FreePBX + SIP configuration

Cisco Packet Tracer / FreePBX

Multi-Network Enterprise (AAA + Controller)

A two-network enterprise design centered on centralized authentication — separating production access control from a dedicated, isolated management infrastructure:

Network 1: AAA Security Services
TACACS+ and RADIUS authentication
Device access control policies
Secure login validation
Network 2: Controller / Management
Dedicated management infrastructure
Isolated from production environment

Cisco Packet Tracer

Cisco ASA Firewall with DMZ

A secure perimeter architecture built around a Cisco ASA, segmenting the network into Inside, Outside, and DMZ zones to expose public services without compromising internal hosts:

ASA interfaces — Inside / Outside / DMZ
Security levels & zone-based policies
NAT rules for DMZ server access
ACLs for inter-zone traffic filtering
Connectivity & security restriction tests
