Re: Cannot Share internet thru dual NICs

Tech-Archive recommends: Fix windows errors by optimizing your registry

The default gateway problem can be fixed by modifying the DHCP scope.
This should be giving the clients the internal IP of the server (ie
192.168.254.1) as the default gateway. After you change it, you may need to
do an ipconfig /release and ipconfig /renew on the clients to get the new
setting.

The second problem is DNS. The clients should be using this same address
for DNS (so that AD works properly). To resolve external addresses, you need
to modify your DNS server to forward requests it cannot resolve itself to a
public DNS service.

The default gateway setting on the LAN NIC should be blank. eg

Internet
|
router
|
10.0.1.1 dg router IP
RRAS
192.168.254.1 dg blank
|
clients
192.168.254.x dg 192.168.254.1

You will also need to add a route to your Internet router. It does not
have an interface in the 192.168.254 subnet, so it does not know where that
subnet is. You need to route traffic for 192.168.254 to the RRAS/NAT router.
eg

192.168.254.0 255.255.255.0 10.0.1.1

Otherwise this traffic uses the router's default route (which is back
out to the Internet!)
