Routers and broadcasts

[Donachie]

Is there any way to get a router to forward broadcasts from a particular client?

Hi,

Not that I know off, 255.255.255.255 is designed to stay local. You can forward directed broadcasts e.g 10.52.255.255( if the routers is set to do so ).

If one server is on network 191.24.1.0. and the other is on network 110.44.0.0, and you want to permit IP broadcasts from all hosts to reach these servers.

interface ethernet 1
ip helper-address 110.44.23.7

this by default works on the following:
69
TFTP
67
BOOTP Client
68
BOOTP Server
37
Time Protocol
49
TACACS
53
DNS
137
NetBios
138
NetBios Datagram

if you want to send another broadcat protocol use
ip forward-protocol udp 2000 for a udp port 2000 broadcast

This would then send all broadcasts to a named host on another network.

If you only want to let one host do this then you need to set up a policy based routing map
