Consider the following network setup in Figure $2.$ Suppose that the ISP assigns the NAT router the address $32\mathrm{.}48\mathrm{.}117\mathrm{.}86$ and that the network address of the home network $($the network behind $($on the right of$)$ the NAT router$)$ is $192\mathrm{.}165\mathrm{.}122\mathrm{.}0/24$ Figure $2$: NAT and addresses a$.$ Assign addresses to all interfaces of the hosts in the home network.

b$.$ Suppose host H $2$ and H $3$ each has two ongoing TCP connections, all to port $80$ at host $128\mathrm{.}116\mathrm{.}60\mathrm{.}72.$ Provide the corresponding entries in the NAT translation table. c$.$ For the first entry related to host H$2$ in the NAT table, fill in the source and destination IP addresses of the message exchanges outlined in the figure. $\backslash$begin$\{$tabular$\}\{|$l$|$l$|$l$|\}$
