Blocking DHCP on Powerconnect 3348
I'm having trouble setting up an ACL to permit one DHCP server and deny all other DHCP traffic. I've looked through the forums and found this...
o 1. console(config-ip-al)# permit-udp 10.0.0.1 0.0.0.0 68 any 67
o 2. console(config-ip-al)# deny-udp any 68 any 67
o 3. console(config-ip-al)# permit any any any
I setup the ACL, then tried applying it to an interface. That didn't work, then I tried applying it to a Vlan. That didn't work either. I tried setting this up using both the GUI interface and the command line, but neither worked.
For some reason, the deny rule works fine, but the permit rule (permit-udp 10.0.0.1 0.0.0.0 68 any 67) is not. I sniffed the traffic to make sure I had the correct IP Address and ports. Is there something that I am missing?
