if that's what you want, you may want to make a copy of snoopy that takes an extra argument "[-c dest]" that copies packets matching the filter to dest. you'll need one snoopy in each direction to do it this way so it may be worth the effort to allow snoopy to read from two input sources and copy packets to the other side. cec(3)'s mux.c has an example of how to read from two input sources and pretend that you're single-threaded. the 83815s on the soekris are a tad pokey, even by 100mbit standards. - erik
