Subject: [NARC] Port forwarding Bittorrent
Message-ID: <20060411183614.1436E7B5BE@ws5-10.us4.outblaze.com>

Hi -

I'm using the Narc 0.7 firewall on my network and am trying to port-forward the ports for bittorrent in the narc-forward.conf file... the line in it I have says:

INTERFACE="";PROTOCOL="tcp";ORIG_IP="AUTOGET_EXTERNAL_IP";ORIG_PORT="6881-6999";NEW_IP="192.168.0.80";NEW_PORT="6881-6999"

But now I'm getting an error:

 iptables v1.3.5: invalid TCP port/service `6881-6999' specified

What's up with this?

I noticed at some point the syntax changed from using a ':' because when I tried it I got:

 iptables v1.3.5: Invalid port:port syntax - use dash

Someone on #netfilter on IRC said to make sure I have the multiport match module, and I do see ipt_multiport in lsmod.

I'm running Slackware -current with Linux-2.6.15.6

Other individual ports I am port-forwarding (port 80 and port 443) work fine.

Any ideas?


Thanks -

Chuck Bell
