What exactly you are asking.. ?
well, when you assign IP address statically to each machine then you don't have to do anything about MAC address as you are manually assigning the IP of your choice to each machine.
If you are asking that I want to allow access to server to only specific computer wich particular MAC and IP then the question is little different.

... so wht actually you are asking .. plz elaborate.

Its rather confusing Jintendra !

I want to make clear that u only need to bind an IP address when u want to allow / deny access to some specific mac to a server.

Like I want that a particular mac address XYZ is not allowed to access internet from my computer then we can do that.. in that way whtever IP is.. but that mac addressed computer will not be able to access the internet.

Other case is when we want to assign specific IP to a particular mac address . then we use dhcp.

Sorry.. but I just want to be little more clear .

so can you tell me wht is ur case ?

Hi ricky
as we can mac bind through dhcp server as we can mac bind without dhcp server. I am sharing the internet through squid. And i configured the static ipaddress to the client system. Now i want the band the mac id with ipaddress for allow to access the internet

Due to apply ACL based on the MAC instead of IP, is this your query on.

There is such option in squid but can't recall at the moment. Will find out and then will tell you.

ya he is asking to allow access to only specific mac address to use internet through proxy.

In squid it is controlled by ARP based acl. I had once tried that only for testing. You will need to compile squid with arp support

Code: [Select]

./configure --enable-arp-acl
Also you can try using arp directive before compiling, may be your binary already compiled for that.

now you can simply use acl for arp as below

Code: [Select]

acl NameOfAcl arp 11:12:13:1a4:15c:1
and then deny or allow that acl.

Ip Assinment it self is process of binding a perticular mac address with a perticular ip.
now if we specify this thing through DHCP than that perticular IP address id binded with the mac address of that mechine for the specific time what ever has been configured on the server .
but if we are providing the ip address manually to that client than its clear meaning is that the perticular ip address is being binded with the mac address of that interface for the time period untill we do not change the ip address so if u want the a mechine should use the network or in other words " a perticular MAC addess could use a specific ip in the network then this can only be done by blocking the permission for users to change their ip address " and this condition can be forcefully be applied thrugh access lists at the server end and this should be done at gateway level it self .
where it will cross verify wather that perticula interface which has a specific mac adderess is using a specific ip or not if condition meets then only the gatway will forword the request other wise it will discurt it.
so to impliment this u need two things
1- at client level user should not be able to change the ip address
2- at gatway level some access list should be applied.
