Broadcast routing (router mode)

Hi,

Is there any possibility MT to route broadcast traffic (255.255.255.255), from one IF nework to other IF network (in router mode) ?
I have a server that is hosted in one net, use broadcast to announce itself, but clients are in other netowrk.
I can’t use bridge mode because of other configuration.

Cisco router has option for forwarding broadcast. How it can be done with MT ?

How pass through PPPOE

Bridge with filter…

Have you tried destination NATing the broadcast? It applies to IP only, of course. Let me know how it goes.

I am not shure, should I use bridge mode for this two interfaces and steel keep routing function (I have to keep two diferent network) ?

You have to choose, if you want Broadcasts then you must Bridge and have same subnet on both networks. If you MUST route with different subnets, then it appears you cannot forward broadcasts.

What kind of Server is doing the Broadcast? If it’s a Microsoft Domain Server then you should be able to setup WINS servers on both subnets that talk to one another and provide the MS Net Broswer facility.

You may actually only need one WINS server, as long as the clients on the “remote” network have a WINS server address pointing to the machine on the “home” network they will redirect their Net Browser requests to the WINS server rather than Broadcasting.

We have some kind of accounting server, that makes announcement to other servers and clients for every event. This announcements are sent via broadcast (255.255.255.255).
Is there any way to tunnel this broadcast with WINS or with MT ?

I just have seen some strange situation.

First net is 192.168.90.0/24
Second is 192.168.1.0/24

When I ping broadcast net for first net 192.168.90.255 I get response from every computer in this net, if I ping broadcast for second net 192.168.1.255 I get response only form MT interface.

I have tried to manualy add FF:FF:FF… mac in arp for this adress but do diferences.

Any idea ?

Of course there is way . Look at DHCP relay , or IP Helper in Cisco. but how it can be done in MK ? No idea
