An obvious answer might be > that the system appends the rule in both FORWARD > chains, (if there is two chains). Nope (thankfully) The MANGLE table's are not for filtering data. Mangle's are typically used for inline parameter modifications like changing the TOS/MSS/etc... The order on any given chain is raw/mangle/filter/nat. Not all tables are run on each chain. Eg. FORWARD table only has mangle/filter.

Yeah, but you can't exepect everyone on a public list to support you just because your talking. It's too bad that nobody got back to you, but it does happen from time to time. You may want to rethink your questions, check external references for more info, make the theme explicitly clear and resubmit. The questions usually get answered eventually. Also note, the questions asked here vary based on their difficulty. You have questions from newbs (which is fine) asking pretty elementary questions and you have the pros that generally aim to ask/solve very technically challenging questions that may/may not involve developing their own programs/modules to solve the problem. I've been on this ML for a while and I can say personally that I'd answer a rare higher difficulty question over a question that's been answered half a dozen times before (I'm not criticizing, its just what happens to most ppl learning). I hope that gives you some insight on the dynamics of mailing lists like this.
