Packet flow through IPFW+IPF+IPNAT ?
Hi.
On my FreeBSD 4.8 configured IPFW2+IPF+IPNAT and I use them all:
- IPFW - traffic accounting, shaping, balancing and filtering;
- IPFilter - policy routing;
- IPNAT - masquerading.
I want to know, how IP-packets flow through all of this components?
What's the path?
incoming: IPFW Layer2 -> IPFW&Dummynet -> IPNAT -> IPFilter ?
outgoing: IPFW Layer2 ->
