We will practice firewall configuration in this task. You want to configure a firewall for your home network. In Zone $2,$ you$$ve got one Web server $(131\mathrm{.}159\mathrm{.}20\mathrm{.}1)$ on TCP ports $80$ and $443,$ and one mail server $(131\mathrm{.}159\mathrm{.}20\mathrm{.}2)$ on TCP port $25.$ Your home users reside in Zone $1.$

Your security policy is as follows:

$1.$ Your home users may freely access any Web service, anywhere, on ports $80$ and $443,$ but only if they initiate the connection themselves $($i$.$e$.$ they are allowed to browse the Web$).$ No one outside Zone $1$ can initiate connections to Zone $1,$ on any port.

$2.$ Everyone, including the Evil Internet, can access the Web $($both ports$)$ and mail in Zone $2.$ However, no host in Zone $2$ can initiate connections anywhere else.

You can use zone names instead of IP ranges. Use $$Ext$$ if you want to refer to the Evil Internet, $$Zone $1$ if you want to refer to Zone $1$ etc. Use $*$ to indicate $$all$.$ If you want to indicate directions, note it in the style of $$Zone $1->$ Zone$2$

Complete the table below to define firewall configuration for the given scenario
