Hi.
I am trying to build a transparent filtering box.
Box is running freebsd 5.4, pf and bridge, this is
the setup:

in
  |
  | em0, 0.0.0.0
-----
|     |
|     |
|     |
-----
  |
  | em1, 10.0.0.1


Bridge config:
sysctl net.link.ether.bridge.enable=1
sysctl net.link.ether.bridge_ipf=1
sysctl net.link.ether.bridge.config=em0,em1


PF config:
int="em0"
ext="em1"
rdr on $int inet proto tcp from any to any port 80 -> 127.0.0.1 port 8080

So, pf redirects http traffic to a web proxy. The IP address on em1 is
needed so the proxy can do web requests by itself.

The problem with that setup is that I can see no packets redirected.
Any points?

Thanks,
Sergey
