The client machines mostly use other ports to access slimserver, which means they establish a connection, something which is almost always doable, you don't have to open ports on a client to let it make connections. On the server box you can open the port (presuming you only run iptables) as root: # iptables -I INPUT -s 192.168.0.0/24 --dport 9000 -j ACCEPT (change 192.168.0.0 to whatever your network is) # iptables-save (to save the changes on rebooting the box) This will allow only people on your network to reach slimserver. Opening a port to the network is not so unsafe, especially since there is a server listening on that port. Only advice I could give is, make sure that slimsrever stays up to date. Hope, this helps Bart
