Problem with configuration

[Rich]

Hello All,

No machines on my network can reach the internet. Setup is as follows:

DSL to Internet
RAS Server sits directly behind DSL router. RAS server:
2 NICs. External NIC (NIC-DSL) gets IP via DSL Router. Always on the
192.168.1.0.
Internal NIC has static IP config. DNS points to Server01. DG is itself.
Internal LAN is currently 192.168.168.0. I've duplicate a MS solution. See
MS KB article 321516.
Server01 has static IP and runs AD/DNS, DHCP/WINS. DHCP serves up
192.168.168.0. DNS points to itself.

When configured like this, nothing gets to the internet. If I browse to the
router (192.168.13.254), I can run good diagnostics (Pings, DNSQuery,
Traceert) from the router to the Internet. I can do neither from any
computer.

I'm thinking 2 problems:
1. Server01 DNS is not forwarding anything to the DSL router, which also is
a DNS server.
2. No routing/passing of packets between the NICs on the RAS server.

Can anyone advise on how to test/verify/correct the above two issues? I
followed another MS article on deleting one of the default objects but
forgot which one. Possibly the root. Anyway, need my DNS to forward to
router DNS.

Seperately, am I better off having 1 server run all the network services
(AD/DNS, RAS, etc)? Should it still sit directly behing the DSL router?
What about opening AD and rest of network open to compromise?


Thanks,
Rich

Thanks for the reply. Useful article. I still need to verify that the RAS
server is passing packets between NICs. With the two NICs having the
following config, what should be in the routing table on the RAS server?
Here is the IP config of the two NICs. What do I have to do in RAS to
ensure packets are being forwarded across the two NICs?

External-NIC Internal NIC
IP: 192.168.1.249 IP: 192.168.168.249
SM: 255.255.255.0 SM: 255.255.255.0
DG: 192.168.1.249 DG: 192.168.168.249


Thanks again
Rich

Remove the default gateway setting from the internal NIC. RRAS does not
like multiple DG settings. The only default route from the server should be
out to the Internet via the external NIC.

Routing between NICs is automatic if IP routing is enabled.
