Routing and Domains

I have two networks (172.16.1.0) (192.168.7.0)

I have two W2K Routers. One for routing between LANs and one for routing
Internet traffic.

In order for the 172 network to get Internet access, do your servers need to
be in the same domain?

TIA,

-Tom
 
The routers do not have to even be joined to the domain. The router is
responsible for forwarding packets, and doesn't care about anything above
the IP layer.
 
Ok, so domains are not my problems then.

But none of my hosts on the 172.16.1.0 network can access the Internet,
but they can ping and be pinged by the 192.168.7.0 network hosts.

Everyone on the 192.168.7.0 network can access the Internet though.

What do I need to do so that the 172.16.1.0 network hosts can access
the Internet?

This is my layout...

RoadRunner INTERNET
|
Cable Modem
|
|
DHCP from RR ISP - NIC1 (into Cable Modem)
RRAS 1 SVR (DHCP, DNS Svr)
192.168.7.1 - NIC2 (Static) (into 3COM Hub 1)
|
|
192.168.7.x hosts (DHCP from 192.168.7.1 Svr)
|
(3COM HUB 1)
|
192.168.7.11 - NIC1 (Static)
RRAS 2 SVR (DHCP, DNS Svr)
172.16.1.1 - NIC2 (Static)
|
(3COM HUB 2)
|
172.16.1.x hosts (DHCP from 172.16.1.1 Svr)

On RRAS1 I installed only NAT and added both my NICs to NAT. My DHCP Svr
gives my clients 192.168.7.1 for ROUTER and DNS. RRAS1 is a DC (SOLO.NET),
I enabled routing in the registry, the properties on the RRAS1 server name
is set to route for LAN and Demand Dial.

I have also assigned a STATIC route of...

172.16.1.0 255.255.255.0 192.168.7.11 using the NIC2 interface

On RRAS2 I installed no routing protocol and my DHCP gives my clients
172.16.1.1 for ROUTER and DNS. RRAS2 is a DC (ROGERS.NET), I enabled routing
in the registry, the properties on the RRAS2 server name is set to route for
LAN only.

There is no static route set on RRAS2.

** I am so close. I went from no hosts anywhere having access to the
Internet,
and no host being able to ping either network, to only the 172.16.1.0
network
not having Internet access - but everyone can ping everyone.

What can I do to enable hosts on the 172.16.1.0 network to be able to access
the Internet?

Thanx for any help anyone can give. It has to be simple, but I am new to
RRAS.

TIA,

-Tom
 
Check you r default gateways... RRAS 1 should have the default gateway of
your ISP. RRAS 2 should have the default gateway of 192.168.7.1.

Also verify the route on RRAS 1 for the 172.16.1.0 network.
 
Ok, I did this and was able to ping Internet IPs but not names (not like
www.usatoday.com)

I then added the DNS server IP of the 192.168.7.0 network (192.168.7.1) and
everything worked!

So now, there must be a DNS issue - it is probably the way I setup my test
network.

On the 192.168.7.0 network I have one W2K Server (new tree in new forest)
SOLO.NET, DNS server, DHCP server, RRAS server.

On the 172.16.1.0 network I have one W2K Server (new tree in new forest)
ROGERS.NET, DNS server, DHCP server, RRAS server.

Even though these are two different networks, could I have made the
172.16.1.0 network server the ONLY DC in the ROGERS.NET domain and have the
server on the 192.168.7.0 network a member server in the ROGERS.NET domain?
Would that work?

TIA,

-Tom
 
You can keep your config the way it is. You can create DNS forwarders to
help resolve the names. ( Solo.Net would have 172.16.1.x as a forwarder,
and Rogers.Net would have 192.168.7.x as a forwarder ) and your internet
forwarders of course to resolve external names
 
Thanx very much for your help - I am a newbie to DNS, how do I create
forwarders on each DNS server?

And with these forwarders in place in DNS, can I remove the IP I manually
put in place for the IP Properties?

Thanx again!

-Tom
