I am trying at the command line to reroute as follows.

iptables -A PREROUTING -d 63.168.228.8 -p tcp -m tcp -j DNAT --to-destination 63.168.229.100

if I then do a list

iptables -t nat -L

I dont see the rule and it is not being applied

wrong table command should be:

Code:

iptables -t nat -A PREROUTING -d 63.168.228.8 -p tcp -m tcp -j DNAT --to-destination 63.168.229.100


-t nat is added. On your initial command since you did not specify a table it defaulted to filter.

Apparently DD-WRT's implementation does not echo out an error on your command

And you'll also have to delete the wrong entry in the process of fixing it.
