flexfax: Moving hylafax outside a firewall

["Andrew Webb" <andrew.webb@rdel.co.uk>]

Hi,
	I've been trialling Hylafax inside a firewall for a while and it worked
fine, I've just moved it outside the firewall and am having some problems
connecting. I put the address in the Hylafax client on an NT machine as
usual, but now I get a message saying

Cannot build data connection. Connection Refused.

I've opened port 4559 and 4558 for TCP on the firewall ... any other
suggestions ?

Cheers

Andy
