ACL to Allow only the DHCP Server

Mohamed Lotfy

Dear All,

I have 3 VLANs (it's an example configration):

1- Vlan 10

     ip address 10.10.10.1 255.255.255.0

     ip helper 10.10.10.15

   Vlan 20

     ip address 20.20.20.1 255.255.255.0

     ip helper 10.10.10.15

   Vlan 30

     ip address 30.30.30.1 255.255.255.0

      ip helper 10.10.10.15

router ospf 1

     network 10.10.10.0 0.0.0.255 area 0

     network 20.20.20.0 0.0.0.255 area 0

     network 30.30.30.0 0.0.0.255 area 0

-------------------------------------------------------------------------

Now I need all clients & network components on VLAN 20 to access everything on VLAN 10.

But for the VLAN 30 clients, I need to access only the DHCP Server on VLAN 10 , and can’t access anything on VLAN 20.

Can I use the ACL to do that? If yes how?

And do I have any other features can help me also?

Thanks,

Mohamed Lotfy
