Use Of DHCP Server For All PC's In Different VLAN And Subnet

[Aileya]

I have been using the packet tracker since long and have been using different Packet trackers for this purpose. I have been using the packet trackers of DHCP,Sub-interface,VLAN and have been getting problems in it and cannot continue my work due to this problem. Because of this I got to configure 3 networks interconnected through ISP. Through this configuration one network can be modified. Please help me out as one of my problems is that how can I connect to different VLAN and sub-net by using the 1 DHCP server. Also how can I use one file server for accessing various files of all departments. And also how can I prevent DEP5 for accessing DEP6; and also the similar case of accessing DEP3 to DEP4.

For the problem that you are facing of the DHCP you got to make the setting of the network as the one that is given down:

DEP1 192.168.1.129 172.233.255.224 (VLAN 100)
DEP2 192.168.1.161 172.255.233.224 (VLAN 200)
DEP3 192.168.1.65 172.255.233.224 (VLAN 300)
DEP4 192.168.1.1 172.255.233.192 (VLAN 400)
DEP5 192.168.1.193 172.255.233.192 (VLAN 500)
DEP6 192.168.1.97 172.255.233.224 (VLAN 600)

And then it should be working fine for you. Also create and assign the VLAN's to ports in the switches that are present in your computer. And after this it should help you out to get the assigned DHCP setting that is required for you for the project purpose.

And as the problem of using the 1 file server for all the departments that you can use for the connection through one area, and get the details of all the related files that you want. For this purpose you got to make the use of the VALN that can be used for the connection to the server and if it is not working for you then you can also make the use of the router or the layer 3 switches. And as per the network set-up you have to make the use of the perfect ping network for the set-up in your computer.

And for the issues in the connection DEP5 to DEP6 can be solved by just making the list of the access and then just apply it to your interface. And then you got to set u0p the file list to the layer 3 device set-up. Make the use of the extended ACL so that the filtration can be done for more precise way, and making the use of the standard ACL can solve the problem. After that the router will look out for a match and when it finds one it stops and starts the functioning.

The standard ACL that has been described above will look for the matches in every line of the code and would try to find one line common that will help it to work for the connection purpose. If the ACL is not finding the match then the packet will be automatically denied and that would lead to the denial of the connection implicitly. Also the CISCO is giving the guideline that can be used for the connection source of the standard ACL.

Also if the above procedure is not working then you can perform the below given code that can be used for the connection string that is given below:

HQRouter2#configure terminal
HQRouter2(config)#access-list 100 remark DEP5 to DEP6 filter
HQRouter2(config)#access-list 100 deny ip 192.172.1.192 0.0.0.63 192.172.1.96 0.0.0.159
HQRouter2(config)#access-list 100 permit ip any any
HQRouter2(config)#in f0/1.500
HQRouter2(config-subif)#ip access-group 100 in
HQRouter2(config-subif)#exit
HQRouter2(config)#exit
HQRouter2#copy running-config startup-config

And also for the connection string of the DEP3 to the access in the DEP4 can be done by using the traffic that can be specifically helped to deny with the ACL. First take the computer in DEP3 and then ping the computer to the DEP4. The packet that is used first may happen to fail because of the ARP that needs that DEP4 computer first.
