Multiple Connections

Thats correct, you need to enable routing in RRAS.

hi every one,
thanks for your help.

now i use [code:1]netstat -n[/code:1] during using internet
so i can see on which interface it connect to internet.

and about [code:1]route print[/code:1] there is the
default gateway at the end of the list, can i change
this default gateway or no? the system choose one of
the connections (the better one) but i don't want it.
i have 2 connections (different IPs), nic1 to access internet
and nic2 to access LAN. If i want use internet how i can
route only internet packets to nic1? and how i can make sure
that my LAN packets not directed to nic1?

The default gateway is the 'route of last resort', i.e the place Windows will forward the traffic to when it has no other routing statement that matches it. So what you need is a set of more specific routes that send the traffic the way you want it to go, then a default route that just points to the internet to make sure that everything else still works

I believe you just need to add a route out to the lan...

like

route add 10.0.0.0 mask 255.255.0.0 10.0.0.1

this assumes your lan is 10.0.0.0 /16

any time you try and access something like 10.0.0.2 you go out to that network and not out to the internet.
