    Analysis of Generic Routing Encapsulation (GRE) over IP Security (IPSec) VPN Tunneling in IPV6
    (Daffodil International University, 2020-09-26) Ferdous, Johan; Islam, Md. Mafiul; Sutradhar, Sajib Chandra
    Over the past years, Virtual private networks (VPN) is an essential technique for providing remotely secure connections to exchange information while IPv6 is the future of the internet. It is superior to the currently reigning version of the internet protocol, Ipv4. But due to the backward compatibility problem of IPv6, is not deployed nationwide yet. In This Project Analysis of GRE over IPSec-VPN Tunneling Over IPv6 is done using GNS3 network simulator connecting two remote offices with IPv4 compatible devices over an IPv6 internet providing a VPN tunneling protocol solution for establishing a private secure network. Which facilitates the IPv6 deployment ensuring co-existence of Internet protocols until IPv6 compatible devices replace the entire old IPv4 compatible devices. The testing and verification analyzing of data packets have been done using the PING tool. Solar winds are used to measure the throughput and Wireshark ensures the encryption of data packets during data exchange between different sites belonging to the same institution. The performance in terms of response time, throughput, and packet encryption of the proposed method is analyzed. The result shows the average response time of 40.372 ms, a throughput in Kbps after transferring ICMP traffic from the source for the router, and finally after the crypto session analysis of the encrypted packet.
