So you have:
[ router ]
|
|
[ BSD box ]
| |
| |
[ web ] [ web ]
[server] [server]
? You'll probably want either routing or bridging enabled on the BSD
box, to handle any DNS lookups or other activity the web servers will
be doing, and with either of those enabled, ipfilter should be able to
process the packets. I've never used ipfilter myself, though, so I
can't say whether this will definitely work or not.
