Well, remember that it's OpenBSD, so you've the source code.Was wondering if anybody know if it is possible to add some Default rules to the kernel or something when compiling..
You can probably do what you're asking for by adding 5 lines of code in net/pf.c inside "case IPPROTO_TCP" in pf_test().
If you want to pay someone to do that for you, you can always mail me privately :) Cedric
