Task 2. The current edge router implementation at RAC is using the less secure Single Router approach (refer Figure 1 in Appendix A), with port forwarding for Web service (HTTP port 80), Domain Name service (DNS port 53) and File Transfer Protocol service (FTP port 21) to host their company's online marketing website engine and company softcopy files.
