Abstract:
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.
