I am now having difficulties with the iptables discussed on the last page of the tutorial. What I need to do is forward all requests on port 3306 to my sql server. Right now this is what I have in /etc/network/if-up.d/iptables

#!/bin/sh

### Port Forwarding ###
iptables -A PREROUTING -t nat -p tcp -i eth0 --dport 3306 -j DNAT --to 10.0.0.2:3306

Even with these settings I am not able to connect to my sql server with a client. Here is the output of iptables -L:

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         
ACCEPT     0    --  api.scratchco.com    anywhere            PHYSDEV match --physdev-in vif1.0 
ACCEPT     udp  --  anywhere             anywhere            PHYSDEV match --physdev-in vif1.0 udp spt:bootpc dpt:bootps

ACCEPT     0    --  hudson.scratchco.com  anywhere            PHYSDEV match --physdev-in vif5.0 
ACCEPT     udp  --  anywhere             anywhere            PHYSDEV match --physdev-in vif5.0 udp spt:bootpc dpt:bootps 

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

Any suggestions?
