Hello experts

I need to connect a remote site to the local Ethernet LAN, using a leased
line (or just possibly an ISDN link). I have seen quite a few
router/bridges which might do the job; however I have the specific
requirement that certain broadcast UDP packets (which my applications use
extensively) be passed over the link. As I understand it most routers would
specifically block broadcast packets for obvious reasons. Of course, I
would need to retain some basic routing capability so that the low bandwidth
link is not saturated by the local network traffic.

Does anyone know of a router that I could configure to pass these broadcast
UDP packets?

Thanks,

Denville.

Yes.

Well, technically routers IGNORE broadcast but think
of them as "blocking broadcasts" is a useful mental picture.

Some of the more (advanced) full service routers
can differently propagate broadcasts based on rules.

Most of the cheap stuff cannot do this or only does it
for very well known broadcasts like DHCP discovery
messages or perhaps NetBIOS broadcasts.

I don't know specific model numbers but you might
look at the big boys like Cisco, HP etc.
