Re: flexfax: RE: Moving hylafax outside a firewall

[Christoph Scheeder <christoph.scheeder@scheeder.de>]

hi,

as far as i know, Hylfaxa uses a FTP-Protokol for transfering data to
the server. The ports 4558 and 4559 are only used for the 
control-connection to the server, data is transfered over an randomly
chosen TCP-Port between client and server.
And that transfer is initiated from the server side...
==> big problem with firewall.
