Very long connecting time

I am just started using netty. I have a simple server binded to two tcp
ports. One of them is telnet and is almoust a copy of a sample telnet server
implementation found in netty src.
I have a remote host with debian (squeeze) with different services started.

When I try to connect to my netty server I got aroung 7 seconds connecting
delay. After that all goes normal. My onConnect handler:

 @Override
    public void channelConnected(ChannelHandlerContext ctx,
ChannelStateEvent e) throws Exception {
    	InetSocketAddress remote =
(InetSocketAddress)ctx.getChannel().getRemoteAddress(); 
    	Server.logger.info("new connection from: " + remote.getHostName() + ":"
+ remote.getPort());
    	
    	// channel is automatically removed from channel group on disconnection
    	Server.allChannels.add(ctx.getChannel());
    }


On the other hand if I try to connect another listening ports on remote
server I got connected without any delay, so that this is not a network
issue.

What could be the probem?
