Hi.

This is how my network is organized:

Internet --> ADSL Modem --> ext_if --> Bridged OPENBSD --> int_if -->
Linksys router WRT54G --> Internal Network

The connection to ADSL is being done by the Linksys router (not by
OpenBSD). So I don't have a tun0 or pppoe interface.

With tcpdump, I get this information for each packet

[...]
10:10:10.316450 PPPoE-Session
code Session, version 1, type 1, id 0xae39, length 42
IP: 200.xxx.xxx.xxx.1935 > 200.xxx.xxx.xxx.xxx: R
1324406928:1324406928(0) win 0
1100 ae39 002a 0021 4500 0028 9353 0000
2e06 19b1 f637 6a1b c8ba 8fd5 0d8f 0050
4e3a 9ae4 4e36 98ed 5004 0000 4aee 0000
[...]

I need to redirect each packet from int_if port 80 to 127.0.0.1 port
8080
I've tried tons of pf rule like :
rdr on $int_if proto tcp from any to any port 80 -> 127.0.0.1 port
8080

I've even tried:
rdr on $inf_if from any to any -> 127.0.0.1

and still nothing...

I want to force each packet from the internal network to be redirected
before going out, and vice-versa for the incoming: redirect it before
coming in.

Any hints will be appreciated.

Thanks in advance,

Nicolas.

Your rules will redirect lan traffic attempting to connect to
$int_if:80 to 127.0.0.1:8080. Then what? What do you have running
there? Some kind of proxy server I guess. As for incoming traffic,
your rules don't apply. Kindly provide more info as to what you are
really trying to do.
