Default Gateways

I have specified 2 Default Gateways (W2K Server) and (am
able to) configure traffic flow by adjusting the Metric on
each link.

If I check the ipconfig, I will only see one gateway
(regardless of which gateway I assign the smallest
metric). Is there a reason for this, am I able to correct
it such that the secondary link is used?

I don't get any traffic at all over the secondary link.
SMTP traffic used to travel across the secondary link (as
SMTP is restricted on the primary link by the ISP).

Thanks.

You can only have one default gateway active at a time. You cannot add a
second default gateway for "some of the traffic". It is an all or none
thing. If the first default gateway becomes unreachable for tcp traffic the
second default gateway will be tried at that time.

W2K will only use one default gateway at a time. If more than one is specified,
it may be used as a backup if dead gateway detection is enabled. You could
however use the route add [use -p to make persistent] command to configure
routes on the other gateway. --- Steve

I have a question along those lines:
I'd like to connect two offices (each with it's own DC and subsequent
intranets) with 2 Win2K "VPN Servers" that are not part of the AD schema of
the respective DC. Each office connects to the Internet through a hardware
router.

My design is based upon the info at:
http://msdn.microsoft.com/library/de...0/html/VPN.asp

If I understand this correctly - the Win2K VPN servers then become thier own
network.

The question I have is - if the Win2K VPN servers become the default
gateways (replacing the hardware routers) for their Intranet but only
handles traffic destined for the other Intranet (through static routing), do
I have to make the routers the DG of theWin2K VPN servers for Internet
traffic?

Basically, how is Internet traffic handled if the VPN servers become the new
default gateway?

Thanks

Why would the vpn servers be replacing the hardware routers?? Usually your default
gateways can remain the same , but they need to have their routing tables configured
to route traffic destined to the remote network to the vpn servers by their internal
ip addresses. --- Steve
