Cannot do site-to-site transers

yuh · 12-02-2002, 11:36 AM

Changed ISP a couple of weeks ago, and since then ive been unable to do site-to-site transfers.
The new modem i got, also includes a router, and im 100% sure the problem lays in that.

The router is a Netopia v4542.
It is impossible to turn off DMZ in it, so i need to know exactly what ports to open/forward.

Im running WinXP if that matters in any way.

The fxp always stalls on this:

250 Directory changed to /dir
PWD
257 "/dir" is current directory.
TYPE A
200 Type set to A.
PASV
227 Entering Passive Mode (xxx,xxx,xx,xxx,13,123)
LIST
150 Opening ASCII mode data connection for /bin/ls.
226 Transfer complete.
TYPE I
200 Type set to I.
TYPE I
200 Type set to I.
PASV
227 Entering Passive Mode (xxx,xxx,xx,xxx,13,124)
PORT xxx,xxx,xx,xxx,13,124

And yes, ive tried to toggle with passive mode on/off, this sites uses NAT, and tried different FXP methods. Always stalls on PORT ...

Anyone have any idea what to change in the router/FlashFXP, or have any experience with Netopia routers?

router shouldn't affect your ability to FXP. forwarding ports will not make any difference to FXP.

what FlashFXP build are you using?
wild guess but if it always stall after PORT command it's possible that your router changes IP address in PORT command from the site ip to your ip.
check your router documentation for any such info.
also check out dslreports netopia hardware forum. they should be able to help you with specific instructions.

A router will prevent you from fxping if it uses NAT (Network address Translations)

Based on what you described I suspect the router/modem is to blame. Unless you can configure the router/modem I'm afraid you're out of luck.

Yes, i can configure the router, and yes it uses NAT.
But, the problem is I dont have a clue on what ports to forward/open. any idea?

It has nothing to do with port forwarding. The fact that it uses NAT is why it doesn't work.
