Hi guys. Have a little problem here that you might be able to help me with. I have a network here that's on the internal block 172.20.0.0/16. On the linux server I'm running a pop3 server. The hosts on the internal network aren't using dns and because of this when client connect to the box they hand. The ip addresses for the clients are handled dynamically and in /etc/hosts.allow I have: all: 172.20.*.* Will this allow the clients to connect or how do I make it so that the dns doesn't time out since I suspect this is what is happening. Thanks. Tommy
