The routing table is set of rules usually written in table format. The routing table stores information about IP networks and how they can be reached. Table is used to determine where date packets travelling over and IP network will be directed. When a packet is received, the packets are examined and matched to routing table for best match for its destination. While using VPN routing table directs packets through the TUN interface. In Lab 7 the kernel needs to decide which network interface the packet should be routed through: eth1 or tun0. Routing table need to be setup correctly for the kernel to pick tun0. Once the decision is made, the kernel will set the source IP address of the packet using the IP address of the network interface In lab 7 we also need to set up the routing table correctly, so the new packet will be routed through the interface eth1; therefore, the source IP address of this new packet should be 209.164.131.32 Routing tables are traversed in a user-definable sequence until a matching route is found and the network stack will copy the packet into the buffer for the corresponding network interface. For IP packets to go through VPN tunnel we want to send the IP packet to the TUN interface, we can simply add a rule to this table to let the network stack direct the packet towards the TUN interface. After a packet reaches the tunnel application via the TUN interface , it will be forwarded to the other side of the tunnel. Ans 4. 10 for telnet using Tun0, for receiving site, what is the source ip it gets? Reason?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
