Re: static routing

OK, I understand, for the most part. On the corporate server, what do I put
in for the gateway on the static route? Here is what I have so far:

Static Route:
Interface (Local Area Connection 2) --this is the only interface available
on the corporate server
Destination: 192.168.17.0
Subnet: 255.255.255.0
Gateway: ?????

The reson it doesn't work is, as I said previously, routing is a two-way
process. A static route will get the traffic from one site to the other,
but what happens to the traffic in the other direction?

As an example, assume that a workstation in one site tries to ping a
workstsation at the other site. The packet goes to the default router
which has a static route pointing to the "other" site via the point to
point link. Everything is fine. What happens when the target machine tries
to reply? As before, the packet goes to the default router for that site.
This router does not have a route for the private IP subnet of the first
site. It tries to send a reply using its default route (which is probably
out to the Internet). The packet is discarded because private IPs cannot
cross the Internet.

Routing between sites will only work if each router has a static route
for the subnet of the "other" site via the point to point connection. In
this case, the privately addressed packet is encrypted and encapsulated
before it is sent out to the Internet. (That is, the private traffic
between the two private subnets is tunnelled through the public Internet).
The traffic in both directions must use the tunnel.

OK, so if I understand you, I need to create a demand dial connection on
both sides and connect them? I still don't understand how the lan users
on the side that already has the dd connection made can't access the
network, but the machine that made the connection can.

To get routing working between the two sites you will need to set up
a site to site (also called router to router) connection. Routing is a
two-way process. You must have routes on the routers at both ends to be
able to get from a host in on site to a host in the other.

To do it using RRAS routers you need one in each site. The connection
is made between the routers. Each router has a static route to the other
site linked to a demand dial interface. The "calling" router connects to
the dd interface on the answering router. The static route thehn become
effective, routing traffic through the link.

Yes, your right. Here is the setup:

Branch Office
Server "WAN"
IP: 192.168.16.11
Subnet: 255.255.255.0
Gateway: 192.168.16.1

Server "LAN"
IP: 192.168.17.2
Subnet: 255.255.255.0
Gateway: "None"

Client IP Setup:
IP: 192.168.17.25
Subnet: 255.255.255.0
Gateway: 192.168.17.2

I used static ip addressing on the clients to make it easier. The
clients can connect to the internet just fine, but can't browse the
remote network. The server already has the demand dial interface
connected and I can browse the remote network from the server, but not
from the clients. I can also browse the branch office server from the
corporate office network (clients or servers). Hope this helps.

Hi,

Am I right in assuming that the Branch office server itself has the
demand
dial interface?
Also, if that is the case, I assume the client PCs have their default
gateway set to the LAN IP Address of the Branch Office Server... is
that the
case?

It may be worth doing a Tracert to ensure that the Client PCs are
going the
correct route.

The Static route needs to specify the Demand Dial Interface as the
'Interface' for the Static Route. Specify destination IP Address and
Subnet
Mask for the remote network.

If you can provide a little more info, I may be able to help more,
sorry
this response is slightly vague.
