What are the values for the IP layer in this network?

Here are my answers so far. I solved for the rest of the table I just do not know what to put in the field for IP layer. Please help!

NET 3 NET 1 Nat 1 NET 2 router 1 Assume the following addresses H1 192.168.5.5 H3 129.186.2.8 Router 3 129.186.4.253 (for NET 2) Router 3 129.186.2.254 (the NET 3) Nat 1 192.168.5.254 (for the NET 1) Nat 1 129.186.4.1 (for the NET 2) Router 1 129.186.4.254 (for the NET 2) Router 1 10.0.0.5 (for the internet side) Assume the NAT is a dynamic NAT and that 192.168.5.0/24 is the internal network Assume the following request packet is delivered to the IP layer from the TCP layer on host H1 with an intended destination of H3. (Assume the other TCP header values are correct) TCP source port = 9333 TCP destination port = 80 500 bytes of data Assume all ARP and DNS tables are current. For each of the points in the network listed below show the values for the following fields in the packets (Assume the initial value of the time to live field is 100 when the packet is sent by either host H1 or H3) (If the value for a field is not specified you can assume a value) Show the fields in the reply packet at each of the points in the network Net 1 (request) Net 1(reply) Net 2 Net2 Net3 Net 3 TCP 192.168.5 129.186.4.2192.168.4.1 129.186.4.25 129.186.4.25129.186.2.25 Layer: 254 53 4 4 4 Source 9333 80 80 80 port Dest port 80 80 80 9333 9333 9333 IP Layer: 100 100+x 100 y 200+x 100+x 200+xty SRC IP10.0.0.5 10.0.0.5 10.0.0.5 192.168.5.25129.186.4.25 129.186.2.25 4 Dest IP192.168.5 129.186.4.2 |129.186.2.25 10.0.0.5 10.0.0.5 10.0.0.5 254 54
