I noticed in a search of the list going back that others reported problems with cttproxy, iptables 1.3, and an error from iptables concerning the invalid arguement of '--on-port'. I don't recall finding and resolutions. I apply the cttproxy patch and the patch applies with no problems, builds with no problems, but insmod refuses to load the module, and I suspect that the failure to load the module is why I am getting the --on-port related errors. Any thoughts on how to fix this?
