to quote man page for saned (which i think is still current):
In addition to the control connection (port 6566) saned also uses a
data connection. The port of this socket is selected by the operating
system and can't be specified by the user currently. This may be a
problem if the connection must go through a firewall (packet filter).
If you must use a packet filter, make sure that all ports > 1024 are
open on the server for connections from the client.
you might try using OpenVPN or some other solution that makes ranges easier.
