hi all i searched in google for a while but no results
occeured to me so it's time to write.I got this
problem i got a netbsd 2.0 ipf dhcpd server and i
installed a internal anonymous ftp under openbsd3.6
the
ftp server is ok inside the lan,but if i want to
connect from the outside through the inside it doesn't
work.Those are my setting
/etc/ipf.conf
pass in from any to any
pass out from any to any
pass in quick proto tcp from any to 192.168.0.0/24
port > 1023 flags S keep stat
e
pass out proto tcp all keep state
/etc/ipnat.conf
map pppoe0 192.168.0.0/24 -> 0/32 proxy port ftp
ftp/tcp mssclamp 1452
map pppoe0 192.168.0.0/24 -> 0/32 portmap tcp/udp
40000:60000 mssclamp 1452
map pppoe0 192.168.0.0/24 -> 0/32 mssclamp 1452
rdr pppoe0 0.0.0.0/32 port 21 -> 192.168.0.2 port 21
ok i read somewhere that the line rdr should have be
at the first line ,but i don't know if it's right
thanks in advance for any help.

First, the two last lines of ipf.conf is
unnecessary since since you pass everything
in/out anyway. (The two first lines.)
Actually, that configuration don't provide any
filter functionality at all. You should disable ipf.
To use ipnat with map/rdr functionality, you need to set
#sysctl -w net.inet.ip.forwarding=1
Have you tried that?
