HTTP is used to access webservers over TCP$.$ A TCP connection is set up between the user browser and the server. The server listens on TCP port $80$ for incoming connection requests. The user end of the connection is on a TCP port number above $1023.$ Suppose you want to configure a packet filter rule set allowing inbound and outbound HTTP traffic and you configure your firewall as in the table below:

$\backslash$table$[[$Rule$,$Direction,Src Addr,Dest Addr,Protocol,Dest Port,Action$],[$A$,$Either,Any,Any,Any,Any,Permit$],[$B$,$In$,$External,Internal,TCP$,80,$Permit$],[$C$,$Out,External,Internal,TCP$,>1023,$Permit$],[$D$,$Out,Internal,External,TCP$,80,$Permit$],[$E$,$In$,$External,Internal,TCP$,>1023,$Permit$]]$

Your internal host in this question has IP address $172\mathrm{.}16\mathrm{.}1\mathrm{.}1.$ Someone tries to send connect to your webserver a remote host $($External$)$ with IP address $192\mathrm{.}168\mathrm{.}3\mathrm{.}4.$

Additionally, assume that a user on your host tries to connect to a remote webserver. Four typical packets for this scenario are as shown below:

$\backslash$table$[[$Rule$,$Direction,Src Addr,Dest Addr,Protocol,Dest Port,Action$],[$A$,$In$,192\mathrm{.}168\mathrm{.}3\mathrm{.}4,172\mathrm{.}16\mathrm{.}1\mathrm{.}1,$TCP$,80,?$
