3 I. Configure DHCP Relay - Now we use Linux SUSE refer to Route to do Relay agent and IPTABLES - First we use SUSE to Relay agent and IPTABLES - Type: yast i dhcp-relay - We type this it will install dhcp-relay automatic. - Type yast lan: to assign IP address all Network Interface Card (NIC) - Assign IP all NIC and select one IP address to connect direct with server For server have to assign Default geteway ( ) to connect between DHCP Relay and DHCP server. Ping connection between DHCP server and DHCP Relay

4 - Type : rcnetwork restart: for restart network service and view Ethernet (eth) Go to edit file (dhcprelay.conf): vim /etc/sysconfig/dhcrelay to add interface card (NIC) - Insert all Ethernet (eth) into this file (dhcrelay file) with IP address DHCP server - Then restart DHCP-Relay Service by: rcdhcrelay restart 1. Use client to testing with connection - Now we use windows XP and assign is Obtain IP or (Dynamic) - This client connect through eth2 (VMnet 3) to broadcast by use both command: Ipconfig /release Ipconfig /renew

5 - Client Get IP address through DHCP-relay. II. IPTABLES On SUSE 1. Variable and allow client ping - Variable is a syntax that we do it for refer name or Ethernet (eth) in linux - Type: rcnetwork restart: to view of Ethernet (eth) in IPtables - Create one to configure IPTABLES and extension.sh by: touch filename.sh: Ex. touch iptables.sh - We can create any path that we want to create this file - Go on this file to Configure IPtables and with configuration that we want to configure.

6 - The first, we have to input those syntax in this file for: Variables and Drop all Policy because it is the easy way to allow next time (Drop all and allow which option that we want to allow Command iptables F or X: it syntax Clear cache and option in iptables. 2. Allow Loopback and Client ping to DCHP Server - Command: Allow Loopback it means allow DHCP server ping them self reply (connection) - In this case if we don t to allow client ping to DHCP server we do not type this command because we have dropped Rule above. - Protocol ICMP is a protocol for ping connection between one system or other system. - Allow client who a cross get IP address from DHCP server it will be allow in iptables to DHCP Server. 3. Established and DHCP (Request IP address) with DNS - Ask the step above all Rule have been Dropped, so now we have to allow client to request IP address from DHCP server with Established. Established and Related: is - For DNS Server we have to allow with syntax below: create two options for staff and student.

7 1. Testing Client get IP across IPTABLES - A client doesn t have IP address so it needs to broadcast and DHCP Relay will receive this broadcast and forward to DHCP server through IPTABLES. - For client: Students =VMnet3 and Staff= VMnet4. - Now we testing with Client (Students) - Testing with DNS server that IPTABLES have been allowed - So now Client (Students) can request DHCP and DNS from DHCP Server across IPTABLES. - Now we testing with Client (Staff) - Staff have to get IP address from DHCP server by IP range: with subnet mask /8 -

8 - After we Client (Staff) broadcast IP address succeed then nslookup to view DNS server - Nslookup have been succeeding with DNS server that allows from IPTABLES. 4. Allow Staff and Student Access FTP server - We can only time with two interfaces but it not easy to control so we should create two options between Staff and Students. - So now syntax above are options with Staff and Students: if in the next time we want to Drop with students or staff it is easier than create one options. 1. Testing with Staff and students access FTP server - Ask in the step above both clients still use those IP address and access to FTP Students: /16 Staff: /8

9 Now we testing with Staff - Go to Web browser type: ftp://ip server then press Enter - This step Staff and Student can access to FTP with authentication user. NOTE: If we nslookup successes so we can also access FTP by input IP address or domain name - Other w ay Staff also type: ftp:// : IP address of FTP - We have to change IP address to Name (CNAME) is easy to remember with students and staff. - So now client can also access FT P without authentication during logged.

10 Now we testing with Student - Now we testing with students to access FTP by domain name. - Both client (Student & Staff) accesses to FTP successes by allow from IPTABLES. 5. Allow Client Remote Server - Now we allow client remote to server. - We have to configure two rule one for Students and other one for Staff. - Now we use Remote Desktop with port 3389: port of Remote Desktop. - We can use on input to server and don t from server reply because we have allow Established and Related above. 1. Testing both client Remote Desktop - After we allow rule above, Now we need to testing with client to remote Desktop - The first make sure that Server have been allow to remote

11 Now we use Students to Remote Desktop - Client (Students) can also remote Desktop according to rule in IPTABLES allow - One more this client have been get IP address from server - Go on Start Manu (in client) select Remote Desktop in Accessories. - Then input IP address Server Press Enter to remote or Connect. - It will be need Password of Server

12 - Then it will show all information in server ask picture below. - So now we have successful with Remote Desktop across by IPTABLES. Now we use Staff to Remote Desktop - For Client (staff) and Students are the same because we have allowed rule in IPTABLES. - So now let to remote with the same step above. - Now staff and Students successes with Remote Desktop. 6. Allow Client Join Domain with AD - Client can join domain according to rule in IPTABLES allow or not - In IPTABLES we need may port to working with Domain (AD) to join such as:

13 TCP: 88,135,139,636,1025,1026 UDP: 88,135,445,389,636 - We use with Allow client Join domain. Now I configure two options it easy to change option later NOTE: some IPTABLES it use not the same those port some use less and other use more then it. 1. Testing Client Join Domain a. Now we testing with Student - Make sure that Client (students) successful with nslookup (DNS) and IP address of Range. - Student IP address rang: up - Go to my computer Properties Computer Name Change. - When we join domain it need authentication (User name & Password) of Server. - It will success if correct with authentication user - When we success please restart this computer and then login user in Active Directory (AD). - Go to server to view user in Active Directory in server. - AD in server (Windows) created user (ad.staff and ad.student)

14 - Now client (ad.student) in Domain (pnc.com) log in with computer name students that have been joined domain.

15 - Now client (ad.student) has been successful with join domain. b. Testing with staff join domain - We do the same step ask step above, with IP address and DNS for nslookup. - Ask the same step above it need authentication user name and Password - Then restart this system to successful with join domain (AD) by across IPTABLES. - Ask picture below staff successes with join domain in (AD)
