flexfax: Re: Moving hylafax outside a firewall

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

hi again,
i think that should be possible, but as i'm no HylaFAX-code-guru
i can not tell it for shure.
i'm only programming another windows client for hylaFax and cause
of that had to cope with the client-server protocol HylaFAX uses.
so you'll have to ask sombody else.
Sorry.
Christoph
