You are given the network administrator role in a campus network. Basic Connectivity in the network is complete, you need not to configure any routing.



There are two type of users in campus, Teachers and Students.
Four Services are there in network with four different servers. You have to secure the network by applying access-control-lists on Campus Router to fulfill the following requirements:

1. Students and Teachers should get IP addresses through DHCP; you have to configure Branch Router to forward Student and Teacher PC's DHCP Request to DHCP Server. 

2. Make sure Student and Teacher PC only get DHCP service from DHCP server.(you have to create an access-list on campus router that only allow helper gateway addresses to access DHCP server)

3. UMS servers should only be accessed through HTTPS protocol.(port 443)

4. Teachers can access both Teacher and Student UMS (with https only).

5. Students can access only Student UMS (with https only).

6. DNS sever is only access by Teachers and Students for DNS service only.

7. Everyone should have full internet access. (Google and Yahoo Servers).

Additionally configure the Branch router and Campus router with enable secret "maatisolutions" in order to get 100% marks.
