your webhost is wrong.
at any one time Flashfxp can have a maximum of 2 connections per site.
one is a control connection, this is where flashfxp and server send commands to each other, this is what you see in the status window.
and during file transfers/directory listing there one connection for data transfer.
with ftp protocol it is simply impossible to have less connections.
flashfxp is not multi-threaded, so it is not opening multiple connections to the same server.

it seems like your webhost's router/ftp server is misconfigured and it doesn't properly close connections fast enough. that would be the reason why they'd see 207 connections when you transfer a bunch of small files in a short period of time and trigger that block.

alternatively, you could try to disable pasv mode for that site. that might bypass your hosts block rules. tho for this to work, if you are using a router, it needs to be properly configured to forward data port range.
