Post by geo » Thu, 08 Jan 2004 16:44:00


I want to forward udp broadcasts across network.
example :

on eth0
i have bcast on port 1234
and i want redirect udp packets
on eth1 on port 1234

the host is a redhat linux "firewall"

do you have any idea ??


1. Seeking Linux UDP broadcast forwarding solution

My organization is using Linux-based router/firewalls. We have an
application that we wish to firewall but it uses UPD broadcasts. Right
now, we have it segregated by a Cisco router but we would like route
through a Linux box. The server sends out a directed UDP broadcast
destined to specific networks like,, etc.

The Cisco router has a 'udp forward' command whereby you specify the
UDP port and it will forward all UDP broadcast traffic seen on the
port. I am seeking a program that will emulate this Cisco feature on a
Linux machine. My company is willing to pay for a programmer to develop
this program if it is not already part of the already available
programs out there.

If anyone can help me with this I will greatly appreciate it.

Thank you.
