I have an OpenBSD 4.1 box acting as a firewall. I want to ftp from a windows
box into the firewall but I get the message "425 Can't build data connection:
Connection refused.". Here's how I have things configured:
/etc/pf.conf
------------
# macros
ext_if="dc0"
int_if="fxp0"
# options
set block-policy return
set loginterface $ext_if
set skip on lo
# scrub
scrub in
# nat/rdr
nat on $ext_if from !($ext_if) -> ($ext_if:0)
nat-anchor "ftp-proxy/*"
rdr-anchor "ftp-proxy/*"
rdr pass on $int_if proto tcp to port 21 -> 127.0.0.1 port 8021
# filter rules
block in
pass out keep state
anchor "ftp-proxy/*"
antispoof quick for { lo $int_if }
pass quick on $int_if
/etc/rc.conf.local
------------------
ftpproxy_flags="-r"
/etc/inetd.conf
---------------
ftp stream tcp nowait root /usr/libexec/ftpd ftpd
-USlln
Here's what I get when I try to ftp in:
331 Password required for mike.
Password:
230 User mike logged in.
ftp> dir
200 PORT command successful.
425 Can't build data connection: Connection refused.
ftp>
What am I doing wrong? thanks for any help.
regards,
Mike
