this is a really complicatged way of doing this..
why not just use divert sockets, like natd?
or, altenatively, if you must do it at link layer,
use netgraph to directly deliver the packets to your daemon..
as to packet delay, if the daemon has a high priority
then, no, it shouldn't slow it down
hi all,
this is about the thread regarding the use of a
freebsd bridge and tap(4) to change the contents
of the frames.
the solution proposed in the list was to use:
net.link.ether.bridge_cfg=fxp0:0,tap0:0,tap1:1,fxp1:1
then you'd write and application to bridge between
clusters 0 and 1.

Hi guys,
I finally got it working - apparently, the taps won't work unless I were to
ifconfig the tap device with an ip address (I don't think an ip address is
actually needed, but the ifconfig probably does some ioctl that is needed to
start up the tap device). I'll try to find what exact ioct

Hi Luigi,
Thanks for response, the vmnet/tap stuff sounds like neat stuff. After reading
the description of tap (from the vtun site), the system seems to make a lot of
sense. However, I'm not sure how vmnet comes into play here - what purpose does
it serve, shouldn't I just be able to read from
Hi Julian,
Thanks for the tip, it looks like netgraph can do what I need to do. I've never
used netgraph before, so I better do some background reading first before
asking any more questions.
I guess once I moved away from the IP layer to the link layer, divert sockets
no longer make that much

We do this and a lot more with netgraph and love the architechture,
thanks goes for the people who did the architechture.
So this qualifies as "somebody knows" :)

Nice. The last one-liner I heard that had such a good pacing to it was the
remark about some politician "being off his meds and out of therapy".

That would be excellent, I might even be in danger of
learning something. I have a buncha Soekris net4501
boxes to play with.

Hi guys,
My first attempts at hacking FreeBSD kernel code has not been very fruitful, so
I'm hoping someone with more experience and knowhow might be able to point out
the mistakes that I'm making.
Firstly, let me explain what I'm trying to do. I'm currently working on a
