Hello, it hapens to me a curious thing and I would like to have your comments and suggestions about it. I have 2 machines. One is the NAT gateway and he other is te client on a hiddent network. hosta is te gateway with IP Address x.y.z.w hostb is the client with IP Address 10.0.0.1 hosta has also an alias IP Address x.y.z.v on the outer (dc0) interface on the inner interface (fxp0) (NIC) it has 10.0.0.254 here is my nat rules on hosta: map dc0 10.0.0.0/24 -> x.y.z.w/32 portmap tcp/udp 10000:20000 map dc0 10.0.0.0/24 -> x.y.z.w/32 rdr dc0 x.y.z.v/32 port 22 -> 10.0.0.1 port 22 tcp so that in this way I Can make a ssh x.y.z.v and I will be automatically redirected to 10.0.0.1 on the hidden network. IT works but here is the big problem. when I ssh x.y.z.v it takes around 3 minutes before prompting me for the password. If I Instead ssh x.y.z.w (the gateway) and then ssh 10.0.0.1 it takes around 5 seconds. How come the response time with NAT is soooo damn slow ?? IS there a way to fix the problem ?? The problem is only in te first ssh authentication step, when SSH communication is established the connection looks fast. thanks Rick To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
