yes the helper-address can be a directed broadcast address. The following are forwarded by default when you add an ip helper-address: Trivial File Transfer (TFTP) (port 69) Domain Name System (port 53) Time service (port 37) NetBIOS Name Server (port 137) NetBIOS Datagram Server (port 138) Boot Protocol (BOOTP) client and server datagrams (ports 67 and 68) TACACS service (port 49)
You can turn any of these off using the global configuration commands: no ip forward-protocol udp 69 no ip forward-protocol udp 53 no ip forward-protocol udp 37 no ip forward-protocol udp 137 no ip forward-protocol udp 138 no ip forward-protocol udp 49 You can forward other ports by adding the command "ip forward protocol " ""Newell Ryan D SrA 18 CS/SCBT"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > IP helper will send NETBIOS broadcast and change the packet to a unicast to > the address given.
