stuck with 2 routers

M

Mike

Here's my problem:

I work at a financial institution with a dedicated link to
our business processor. We are running SBS 2002 with 2
NIC's, and also running Exchange 2000.

They have installed a frame relay to a Cisco router linked
to their headquarters in California. They assigned static
IP's to all workstations and utilize IIS to communicate
through the router to their HQ. They originally assigned
a static IP to the server and entered their DNS
information in the NIC properties. This reallly messed up
my DNS server.

I have since removed the DNS entries, reestablished DNS
services and forwarded their DNS IP's. That problem is
solved.

I now want to add a DSL link to the internet and am lost
in the mix of things.

Here's the topology:

The Cisco router is attached to the network switch which
in turn is connected to the internal LAN.

Server NIC1 IP 10.137.201.5
subnet mask 255.255.255.0
Default Gateway 10.137.201.1
DNS servers 10.17.10.18
10.17.10.19

The second NIC is connected directly to the
firewall/router which in turn is connected via public
static IP to the DSL router

Server NIC2 192.168.0.5
subnet mask 255.255.255.0
no default gateway specified
DNS server 216.174.212.5
216.174.212.6

I can ping only the NIC1 from any node on the network. I
cannot resolve internet domain names from any workstation.

I can ping the firewall/router IP address from the server,
but not an IP address external to the firewall router.

Connectivity to the internal LAN/Cisco routed network
works fine from any node or the file server.

Any assistance would be greatly appreciated.

Thanks in advance,
Mike H
I have enabled RRAS as an internet server (no ICS) and am
at a loss at this point.

I would like some assistance in providing the proper
routing to make the internet and email aailable to my
network clients.

Internet----router/firewall----server NIC2

For this to work, your RRAS router must be the default gateway of your
LAN. All LAN clients must be set to point to it. Traffic for HO will need
extra routing info
to get to the Cisco. You can add this to each client, or just add it to the
RRAS router.

For name resolution to work properly, all LAN clients should point to
your local DNS. Your local DNS should be set to forward to some other DNS
server which can resolve "foreign" addresses. Just putting the ISP's DNS
address on the server's NIC doesn't help the LAN clients. (That solution
will only work with ICS, which is set to relay DNS requests).

You don't neeed to run the RRAS server as an Internet server. The
firewall/router is in fact your Internet router (doing NAT etc). Your RRAS
router is simply a LAN router connecting the LAN to the 192.168.0 subnet.

Internet
|
firewall
192.168.0.1
|
192.168.0.5 dg 192.168.0.1
RRAS
10.137.201.5 dg blank
|
workstations
10.137.201.x dg 10.137.201.5
|
Cisco
10.137.210.1

You will need to add a static route to the firewall so that it knows how
to reach your LAN machines eg

10.137.201.0 255.255.255.0 192.168.0.5

You also need extra routing so that your LAN clients know how to reach
the HO site. eg

10.0.0.0 255.0.0.0 10.137.210.1

You can add this route to each client, or you can just add it to the
RRAS router. The RRAS router will redirect HO traffic to the Cisco and send
all other traffic to the firewall.

To avoid name resolution problems, make sure that the 192.168 interface
of the server has Netbios over TCP/IP disabled, and that it is not set to
register itself in DNS. You only want its 10.137 IP appearing on the LAN.

Bill Grant:

I followed your instructions to the letter (well, I
modified them a little because the original default
gateway was 10.137.201.1 not .210.1)

I reconfigured the RRAS to be a LAN router and added the
route as suggested. No internet access. I can ping by
IP address both sides of RRAS from any node. I can ping
by IP address either of the x.x.x.1 firewall or Cisco
routers. I cannot ping by any domain from any node or
the server.

After making the gateway, DNS, changes I seems to have
messed up my DNS as well.

Here are the route tables:

I'm fairly certain I've messed something up, especially
since I had DNS running without error before making the
suggested changes.

I will probably kill DNS and recreate tomorrow morning.

Any suggestions from the data presented? Is there
anything else I can provide to troubleshoot this
further? Sorry to be such a bonehead!

Thanks again for your assistance.

Regards and thanks,

The LAN routing looks OK. The firewall setup looks odd. Is it configured
to act as an Internet router? Does it do NAT? (It needs NAT to translate the
private IPs to public). It doesn't appear to have a default route to the
Internet. I would expect to see something like

0.0.0.0 0.0.0.0 xxx.xxx.xxx.234

For this to work, your RRAS router must be the default gateway of your
LAN. All LAN clients must be set to point to it. Traffic for HO will need
extra routing info
to get to the Cisco. You can add this to each client, or just add it to the
RRAS router.

For name resolution to work properly, all LAN clients should point to
your local DNS. Your local DNS should be set to forward to some other DNS
server which can resolve "foreign" addresses. Just putting the ISP's DNS
address on the server's NIC doesn't help the LAN clients. (That solution
will only work with ICS, which is set to relay DNS requests).

You don't neeed to run the RRAS server as an Internet server. The
firewall/router is in fact your Internet router (doing NAT etc). Your RRAS
router is simply a LAN router connecting the LAN to the 192.168.0 subnet.

Internet
|
firewall
192.168.0.1
|
192.168.0.5 dg 192.168.0.1
RRAS
10.137.201.5 dg blank
|
workstations
10.137.201.x dg 10.137.201.5
|
Cisco
10.137.210.1

You will need to add a static route to the firewall so that it knows how
to reach your LAN machines eg

10.137.201.0 255.255.255.0 192.168.0.5

You also need extra routing so that your LAN clients know how to reach
the HO site. eg

10.0.0.0 255.0.0.0 10.137.210.1

You can add this route to each client, or you can just add it to the
RRAS router. The RRAS router will redirect HO traffic to the Cisco and send
all other traffic to the firewall.

To avoid name resolution problems, make sure that the 192.168 interface
of the server has Netbios over TCP/IP disabled, and that it is not set to
register itself in DNS. You only want its 10.137 IP appearing on the LAN.

The LAN routing looks OK. The firewall setup looks odd. Is it configured
to act as an Internet router? Does it do NAT? (It needs NAT to translate the
private IPs to public). It doesn't appear to have a default route to the
Internet. I would expect to see something like

0.0.0.0 0.0.0.0 xxx.xxx.xxx.234

Bill Grant:

I followed your instructions to the letter (well, I
modified them a little because the original default
gateway was 10.137.201.1 not .210.1)

I reconfigured the RRAS to be a LAN router and added the
route as suggested. No internet access. I can ping by
IP address both sides of RRAS from any node. I can ping
by IP address either of the x.x.x.1 firewall or Cisco
routers. I cannot ping by any domain from any node or
the server.

After making the gateway, DNS, changes I seems to have
messed up my DNS as well.

Here's my problem:

I work at a financial institution with a dedicated link to
our business processor. We are running SBS 2002 with 2
NIC's, and also running Exchange 2000.

They have installed a frame relay to a Cisco router linked
to their headquarters in California. They assigned static
IP's to all workstations and utilize IIS to communicate
through the router to their HQ. They originally assigned
a static IP to the server and entered their DNS
information in the NIC properties. This reallly messed up
my DNS server.

I have since removed the DNS entries, reestablished DNS
services and forwarded their DNS IP's. That problem is
solved.

I now want to add a DSL link to the internet and am lost
in the mix of things.

Here's the topology:

The Cisco router is attached to the network switch which
in turn is connected to the internal LAN.

Server NIC1 IP 10.137.201.5
subnet mask 255.255.255.0
Default Gateway 10.137.201.1
DNS servers 10.17.10.18
10.17.10.19

The second NIC is connected directly to the
firewall/router which in turn is connected via public
static IP to the DSL router

Server NIC2 192.168.0.5
subnet mask 255.255.255.0
no default gateway specified
DNS server 216.174.212.5
216.174.212.6

I can ping only the NIC1 from any node on the network. I
cannot resolve internet domain names from any workstation.

I can ping the firewall/router IP address from the server,
but not an IP address external to the firewall router.

Connectivity to the internal LAN/Cisco routed network
works fine from any node or the file server.

Any assistance would be greatly appreciated.

Thanks in advance,

I'm fairly certain I've messed something up, especially
since I had DNS running without error before making the
suggested changes.

I will probably kill DNS and recreate tomorrow morning.

Any suggestions from the data presented? Is there
anything else I can provide to troubleshoot this
further? Sorry to be such a bonehead!

Thanks again for your assistance.

Regards and thanks,
Mike

For this to work, your RRAS router must be the
default gateway of your
LAN. All LAN clients must be set to point to it. Traffic
for HO will need
extra routing info
to get to the Cisco. You can add this to each client,
or just add it to the
RRAS router.

For name resolution to work properly, all LAN
clients should point to
your local DNS. Your local DNS should be set to forward
to some other DNS
server which can resolve "foreign" addresses. Just
putting the ISP's DNS
address on the server's NIC doesn't help the LAN
clients. (That solution
will only work with ICS, which is set to relay DNS
requests).

You don't neeed to run the RRAS server as an
Internet server. The
firewall/router is in fact your Internet router (doing
NAT etc). Your RRAS
router is simply a LAN router connecting the LAN to the
192.168.0 subnet.

Internet
|
firewall
192.168.0.1
|
192.168.0.5 dg 192.168.0.1
RRAS
10.137.201.5 dg blank
|
workstations
10.137.201.x dg 10.137.201.5
|
Cisco
10.137.210.1

You will need to add a static route to the firewall
so that it knows how
to reach your LAN machines eg

10.137.201.0 255.255.255.0 192.168.0.5

You also need extra routing so that your LAN clients
know how to reach
the HO site. eg

10.0.0.0 255.0.0.0 10.137.210.1

You can add this route to each client, or you can
just add it to the
RRAS router. The RRAS router will redirect HO traffic to
the Cisco and send
all other traffic to the firewall.

To avoid name resolution problems, make sure that
the 192.168 interface
of the server has Netbios over TCP/IP disabled, and that
it is not set to
register itself in DNS. You only want its 10.137 IP
appearing on the LAN.

Here's my problem:

I work at a financial institution with a dedicated
link to
our business processor. We are running SBS 2002 with 2
NIC's, and also running Exchange 2000.

They have installed a frame relay to a Cisco router
linked
to their headquarters in California. They assigned
static
IP's to all workstations and utilize IIS to communicate
through the router to their HQ. They originally
assigned
a static IP to the server and entered their DNS
information in the NIC properties. This reallly
messed up
my DNS server.

I have since removed the DNS entries, reestablished DNS
services and forwarded their DNS IP's. That problem is
solved.

I now want to add a DSL link to the internet and am
lost
in the mix of things.

Here's the topology:

The Cisco router is attached to the network switch
which
in turn is connected to the internal LAN.

Server NIC1 IP 10.137.201.5
subnet mask 255.255.255.0
Default Gateway 10.137.201.1
DNS servers 10.17.10.18
10.17.10.19

The second NIC is connected directly to the
firewall/router which in turn is connected via public
static IP to the DSL router

Server NIC2 192.168.0.5
subnet mask 255.255.255.0
no default gateway specified
DNS server 216.174.212.5
216.174.212.6

I can ping only the NIC1 from any node on the
network. I
cannot resolve internet domain names from any
workstation.

I can ping the firewall/router IP address from the
server,
but not an IP address external to the firewall router.

Connectivity to the internal LAN/Cisco routed network
works fine from any node or the file server.

Any assistance would be greatly appreciated.

Thanks in advance,
Mike H
I have enabled RRAS as an internet server (no ICS) and
am
at a loss at this point.

I would like some assistance in providing the proper
routing to make the internet and email aailable to my
network clients.

Internet----router/firewall----server NIC2

Bill:

Here's how simple the soution was....

The DSL router circuit was down (though the router showed
it as trained up).

Power cycled the router after the ISP resolved things on
their end and presto! Internet access from all nodes!

Thanks for your assistance. I hope I can share what I
learned with someone else down the road.

Regards,
Mike
