Blocking un-necessery UDP traffic when using IP helper address
My branch office network with workstations is contacting my DHCP server in datacenter across a T1 link for getting their IP addresses.I've enabled forwarding of DHCP request from client network router using IP helper address.
By default when i use IP helper address command some eight protocol traffic gets forwarded ..right?
Is there a way to block a few of them which are not required? Is the solution access list at router or a command associated with IP helper address which disables some port from the list of eight.
When i use IP helper address pointing to a particular host does the router carry the broadcast to only that single host or to the entire network in which the host sits?
