Computer Network Projects

Project 1 - IPsec VPN

Created an IPSec based Virtual Private Network (VPN) for a company to connect with its partner's network securely. The data transmitted is authenticated and encrypted over the Internet so Confidentiality, Integrity, and Availability can be achieved.

Configuration includes:

• Type of VPN: IPsec tunnel
• Tunnel policy: Internet Security Association and Key Management Protocol (ISAKMP-IKEv2)
• Failover plan: Port-Channel and Double-Homed Single ISP (WAN topology)
• Packet filter: Extended Access-List
• IP addressing scheme: Internet Protocol Version 4 (IPv4)

Project 2 - Port Address Translation

Implemented a simple network scenario of Port Address Translation (PAT) with Access-List (ACL) which will allow us to translate the private IP address into a public IP address (vice versa. It uses different port numbers instead of a specific IP address. This will help the company to save money as the least or no extra IP addresses needed to be leased from Internet Service Provides.

Configuration includes:

• IP translation method: PAT
• Packet filter: Standard Access-List
• IP addressing scheme: IPv4
• Routing protocol: Routing Information Protocol (RIPv2)
• Other: Dynamic Host Configuration Protocol (i.e. DHCP)
