IPTABLES configuration for tarsnap

[Max Hennig <maximilianrh@googlemail.com>]

Hello,

I have configured my iptables rules the following way:

$FW -A INPUT -i eth0 -p tcp --dport 9279 -m state --state
ESTABLISHED,RELATED -j ACCEPT
$FW -A OUTPUT -o eth0 -p tcp --sport 9279 -m state --state
NEW,ESTABLISHED,RELATED -j ACCEPT

As the port 9279 was described somewhere on the tarsnap website but I
can't find it anymore. It looks like I was missing something as these
rules do not seem to be enough because I still get errors from tarsnap
saying:

tarsnap: Too many network failures

Does anyone know what exactly is required by tarsnap or maybe send me
his iptables configuration (only those parts regarding tarsnap).

Thanks

Robert
