Configuring Subnet Access
Leo selects the Subnet Access item in the left menu. This screen determines what subnet-to-subnet traffic can occur.
The subnet access defaults every subnet having access to every other subnet and full access to the WAN. Leo wants to
restrict subnet access to that marketing has no access to the engineering subnet and no access to the administration subnet.
He would also like to restrict all of the subnets to HTTP, SMTP, and POP access to the WAN.
First Leo will restrict access from the marketing subnet to the other subnets. He selects the cell in the matrix defined by
From Mrkt-SN on the left and by To Eng-SN above. Then, in the Rules section, he pulls down the menu to the left of all
protocols and selects Deny. This will block all traffic originating in the marketing subnet and going to the engineering subnet
except the named protocols. No protocols were selected, so no traffic will be allowed.
Leo clicks on the Apply button to record this subnet access configuration.
