problem transfer files

[torlas]

Hi

I`m new here and not knowing so much about fxp.
Anyway, my friend an me have tried transfer files between 2 servers for some time now. I have no problem doing this. I can add and send files both way, but he can`t do anything but dowloud files to his local pc. However, the same problem occure when I take my laptop over to his local network at his home.

My first thought is of course that it`s a local networks problem, but I wonder why a local network should interfere up to a transfer like this. As long as he can manage to move files down to his local pc from any of this servers. I just can`t understand what`s wrong. He has tried to deactivate his firewall as well, but configurate his router correctly, we do not know how to do.

I use Flashfxp 3.4.0 and he use version FlashFXP v3.7.8 build 1332 [BETA]

Here is some from the log file:

his router is intercepting ftp commands and rewrites PORT commands so that instead of it having IP of the other site, such router thinks that your ftp client is sending wrong IP and replaces it with its own.

if you can, disable this feature in the router, or move ftp to another port where hopefully router won't do that, or enable encryption so that router can't see raw commands you are sending.

Hi

Thanks a lot for quick answer

Have no acess to do any change in the server. We just pay for a sharing seedbox and can only dispose some disk size at this server.

About doing something in the router we have tried, but it seem to be difficult.
I think the soloution is to change his router to a more updated one.
Gues he can get a new from his internet provider.

Anyhow, I still dont see why a router at home should interfer with connection between 2 ftp servers.?

However, I`m just a ordinary man with a slight knowlegde about this.

Again Thank for u answer!!

during regular ftp session when you transfer a file, ftp client will send a PORT command that should contain your internet IP. some ftp clients don't know the difference between internet ip and local ip, so they will mistakenly send PORT command with an ip from your lan(192.168.0.x or whatever other range you use). your router thinks its helping you by modifying this PORT command with any ip address to your internet ip, allowing downloads or uploads to work.
during FXP transfers you know what PORT command should contain, however your router doesn't, so it still blindly modifying that command.

Thank you!...Very good and detailed explanation ;-)

[torlas]

For a lifetime license for software that is daily use for a lot of people here the price is very good.
