RE: Help needed with NAT on Winroute Pro

["Andy Powell" <Andy@xxxxxxx>]

Keith,

sorry about the late response, I've been distracted a little recently,....

First up (and it's probably been said already) your other machines on your
lan have probably got a default gateway of your winroute machine. so when
they try to connect to and external website your winroute machine will dial
out.

You can look at your routing info on your winroute PC using the command
line ROUTE PRINT which will show the NT/Win9x routing tables.

On a client of the winroute system the first line would probably be
something like

Network Address          Netmask  Gateway Address        Interface  	Metric
0.0.0.0          	0.0.0.0      192.168.0.1      	192.168.0.4       1

this basically means that any packet is routed to 192.168.0.1 - the metric
is like a priority 1 = high ....10 = low. what this means is that you can
effectively say something like

use this route first (metric 1) and if you don't get what you want try this
route (metric 2).

On your winroute machine make sure that the ROUTE PRINT line for 0.0.0.0
does NOT have something like this:

Network Address          Netmask  Gateway Address        Interface  	Metric
0.0.0.0          	0.0.0.0      212.145.4.49      	212.145.4.49       1

What that means is that any time this machine tries to connect to ANY
machine (even those on your lan) it would want to dial! What you need is
something along the lines of:

Network Address          Netmask  	Gateway Address        Interface 
	Metric
192.168.0.0      255.255.255.0     192.168.0.1      		192.168.0.1	1
0.0.0.0          	0.0.0.0      	212.145.4.49      	212.145.4.49     3

which would effectively say first up if it's a 192.168 address use my
internal (192.168.0.1) interface. If it's not then dial

Does this make sense??
