Hi,
I've got a sort of problem here, I'm trying to connect
to ftp server hdd.takas.lt the server allows
connections from *.takas.lt addresses only. So what
I'm doing is the following.
I set netbsd IPNAT(not sure if right though) on
machine(let's call it gateway) that can connect to
hdd.takas.lt. relevant ipnat.conf from gateway:

rdr pppoe0 from 0.0.0.0/0 to gateway port = 8080 ->
212.59.13.36 port 21
(where's gateway is IP address of my gateway machine,
212.59.13.36 is hdd.takas.lt)

so I do following from any machine that is allowed by
gateway to connect to any port > 1 :

-bash-3.00$ ftp -ad uogiene.no-ip.org 8080
Connected to uogiene.no-ip.org.

211 END
features[FEAT_FEAT] = 1
features[FEAT_MDTM] = 1
features[FEAT_MLST] = 0
features[FEAT_REST_STREAM] = 0
features[FEAT_SIZE] = 1
features[FEAT_TVFS] = 0

got remotepwd as `/'
ftp> cd incoming

250 CWD command successful.
---> PWD
257 "/incoming" is current directory.
got remotepwd as `/incoming'
ftp> mget *
---> EPSV
'EPSV': command not understood
disabling epsv4 for this connection

 that's it... it just stops...
 so I'm trying to force connection to active mode (-A)
 
-bash-3.00$ ftp -adA uogiene.no-ip.org 8080
Connected to uogiene.no-ip.org.

I don't know how to explain that, I'm not good at
IPNATTING, but as far as I understand ACTIVE
connection should work, unless it's not supported by
the server (which I think what it is...) so I'm
wondering how am I supposed to go about this problem?
thanks everyone for help.
