Unhappy p3scan with PF --> Target IP PROBLEM!!

Hi, I'm Nicola from Italy...
I installed on my freebsd 6.2, P3Scan 2.3.2
It works properly only if specific manually and statically:
targetip = IP address MY PROVIDER
targetport = 110
Although I created the rule firewall PF:
rdr on rl0 proto tcp from rl0:network to any port 110 -> 127.0.0.1
port 8110
does not work ...
Output p3scan in debug mode:
-------

Server p3scan[513]: Connection from 10.0.0.2:60938
Server p3scan[513]: Real-server adress is 0.0.0.0

Server p3scan[513]: Cannot connect to real-server

-------

or, on another machine

-------

Server p3scan[513]: Connection from 10.0.0.2:60938
Server p3scan[513]: Real-server adress is 10.0.0.1

Server p3scan[513]: Oops, that would loop! ... -------
Can you help?
THANKS

Nicola

Code:
rdr on rl0 proto tcp from rl0:network to any port 110 -> 127.0.0.1 port 8110
assuming this is your whole working pf.conf rules set, then you need to edit it...

Code:
rdr on rl0 proto proto inet tcp \
 from rl0:network to any port 110 \
 tag MYRDR110 -> 127.0.0.1 port 8110
# ...
pass in log quick on rl0 inet proto tcp \
 tagged MYRDR110 keep state
#
An RDR statement -- by itself -- does not grant a pass; it should have a companion pass statement.

thank you for answer... I but I've tried something similar:
Code:
rdr pass on rl0 proto tcp from rl0:network to any port 110 -> 127.0.0.1 port 8110
I can not find a solution .. now there are days that fight ..

You need to post more info for more help.

  1. Your whole pf.conf
  2. Edit your nat, rdr, pass and block stmts to include the "log" keyword, and
  3. run the following, capture a test, and post the output here.
Code:
# tcpdump -eni pflog0
/S

ok ...
afternoon place everything that I asked you.

I wanted to know that, perhaps I can not access the file pf.conf, because use pfSense (distro firewall based on FreeBSD)

humm ... I'm not sure about any pfsense-specific diagnostic steps or options.

It's not that you can tell me what are, for each regular following iptables, the rules that match in PF:

Code:
iptables -t nat -A PREROUTING -p tcp -i eth0 --dport pop3 -j REDIRECT --to 8110
iptables -t nat -I OUTPUT -p tcp --dport 110 -j REDIRECT --to 8110

Ah, ...

Code:
rdr on rl0 proto proto inet tcp \
 from any to (rl0:0) port 110 \
 tag MYRDR110 -> 127.0.0.1 port 8110
# ...
pass in log quick on rl0 inet proto tcp \
 tagged MYRDR110 keep state
#
I believe we need to turn the from and to values around.
