Hello,
I have to shutdown a proxy server for a few days and I need to
redirect its traffic to a server behind an iptables firewall. Here's
what I want to do:

But I'm having problems with the second part. The SNAT rule:
-I POSTROUTING -s 192.168.0.3 --sport 2050 -o eth0 -j SNAT --to
130.17.174.108
#This one seems OK too.
-A PREROUTING -i eth0 -p tcp -d $PUBLIC_IP --dport 80 -j DNAT --to
$PRIVATE_IP:2050
The SNAT rule generates the error:
Applying iptables firewall rules: iptables-restore v1.2.11: Unknown
arg `--sport'
I think the difference is that the SNAT rule does not
specify the protocol the way the DNAT rule does ( -p tcp ).
You can only specify a source port for a
protocol that uses the concept of a "port".
Could someone provide help to solve this problem?
