What does "Site uses IP Masq/NAT/Non-Routable IP" actually do?

Por_Que2k · 02-18-2003, 06:01 PM

I just recently found out about this feature, which has helped me out a lot in send files to people who are behind routers, as I am firewalled.

Anyway, I'm just wondering how this actually works. What does it do to allow this to work?

[14:37:43] PASV
[14:37:43] 227 Entering Passive Mode (192,168,1,107,4,239)

Maybe I don't know enough about FTP, but I don't see how FlashFXP can do anything with that.

Thanx for any info!

you sent PASV command
server replied with
227 Entering Passive Mode (192,168,1,107,4,239)
as you can see server replied with it's internal ip address. when you enable this option FlashFXP will understand that that ftp server is misconfigured and instead of 192.168.1.107 it should use correct ip to connected to.

Ah, I had a feeling that that's how it worked. Thanx for the confirmation

I wonder if it'd be posible to have flashFXP do that automatically... since there no way an FTP can be properly telling you it's IP if it's 192.168.*.*. That's an internal LAN only IP. If Flash automatically used the IP that the bookmark was configured with, it'd work in all situations... even when the FTP actually is being run from the LAN.

Maybe I'm missing something though... otherwise I'd guess that it'd be enabled by default.
