Subject: Forwarding multiple UDP ports
Date: Fri, 22 Sep 2006 12:17:29 -0400	[thread overview]
Message-ID: <45140C99.8040205@samera.com.py> (raw)

Hi,
I have a intranet server that initiate UDP connections and I want to forward
those connections to and Internet IP.

I have a Linux box with 2 NICs.

My question is: can I forward UDP trafic from and internal server to the 
Internet?
Can I use this line:

iptables -t nat -A PREROUTING -p udp -s INTRA_SERVER -d INTRA_ROUTER 
--dport 1024:6000 -j DNAT --to-destination INET_IP:1024-6000

I'm testing it and I see the rule matched, the byte and packet counters 
are incrementing.
But, I see no traffic going out of the Internet NIC.
I'm not sure if the multi-port specification will work.

Thanks!
Oliver
