How to set Default Gateway for a connection using RRAS and NAT

Hi all...

I have had problems in configuring RRAS to allow LAN client computers to
connect to Internet using the Internet connection present in the server.
Maybe I have found the cause of the problem. Believe it or not, I have tried
this for looong time... several months and I always end in configuring ICS
back, which always works.

When I enable ICS, all works perfectly, that is, all LAN computers can
browse Internet without any problem. When I disable ICS and enable RRAS, all
LAN continue working, but computers cannot browse Internet anymore.

I have compared IPCONFIG /ALL information, routing tables and even PathPing
information when using ICS and RRAS and all looks identical, except one
little detail.

In the IPCONFIG /ALL in the server, when ICS is enabled, it is shown a
default gateway address, which is the address assigned by the ISP. When
using RRAS, Default gateway information is blank. I think that is the cause
that when I PathPing an internet site from a LAN computer, packet only
reaches server, but it doesn't reach internet interface.

For instance, this is the IPCONFIG /ALL concerning internet Interface when
using ICS:

PPP adapter Manquehue:

Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : WAN (PPP/SLIP) Interface
Physical Address. . . . . . . . . : 00-53-45-00-00-00
DHCP Enabled. . . . . . . . . . . : No
IP Address. . . . . . . . . . . . : 200.119.229.94
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . : 200.119.229.94
DNS Servers . . . . . . . . . . . : 200.74.160.103
200.74.160.104
NetBIOS over Tcpip. . . . . . . . : Disabled

And as I said, when I enable RRAS, Default gateway field appear blank.

If ICS can set that value automatically, I think that using RRAS and NAT is
also possible (manually).

Please, don't point me to some URL's because I have read a lot about RRAS
and NAT, following all directions textually, but no site talks about the
architecture I have in my server.

Thanks
Jaime

Since Tthe DHCP Enable is No, I am assuming you have static IP. Did you assign IP information manually? How do you setup RRAS or which option?

could you possibly run more google ads if you tried? does pointing people to your url's in every post actually make you money?

Robert,

I don't have static IP. Each time I connect to my ISP, it assigns me a new
IP (I connect to my ISP through a DSL router connected to a NIC in the
server). That's why I cannot set default gateway manually using Network
connections.

I wonder, the same as you, why DHCP enabled appears No.

Phillip, as I wrote, I have followed a lot of guides, the third link among
them, with no success.

Concerning all the documents, I have some main differences:

1.- I have no dial-up interface because what I have is a DSL router, it has
the static IP address of 192.168.1.1. So, I cannot follow instructions for
setting up a dial-up connection using RRAS (in fact, I have followed them,
but obviously without success)

2.- Since I have a DSL router, I created a WAN/PPP connection under Network
Connections. After connected to my ISP I run RRAS wizard. In this case, I can
never add that WAN/PPP interface so that I can enable LAN internet connection
on it.

3.- From RRAS/NAT point of view, I have 2 internal NIC's on my server. One
connected to the LAN and the other connected to the DSL router. The DSL
router is actually the public interface that connects to Internet.

Do you have other suggestion? or.. do you know how can I know the exact
configuration made by ICS? If I manage to imitate what ICS has set up, I
think I could do RRAS to work, hopefully.

Thanks
Jaime

If your DSL router's internal IP address is 192.168.1.1, THAT is the default
gateway for your server. Manually enter it on the network connection for
your server.

Thank you for the update.

can I also assume that the server can access the internet but no comuters behind the NAT? I had one case like this but can't remember the solution. is some things to do with DLS and windows NAT. Which DSL model do you have? some details of DSL configuration may help.

Thanks Eric....

Concerning default gateway, I paste here the IPCONFIG /ALL for the server
when ICS is enabled (allowing LAN computers to connect to internet). As you
see, 192.168.1.1 IP isn't shown anywhere. I knew that DSL modem has that IP
because I searched on Internet about this DSL router and I knew that default
IP is 192.168.1.1, and in fact, if I ping 192.168.1.1 I get response (that's
why I configured Internet interface, the one that connects to the DSL
router, to be in the same network segment). Anyway, When I configure
Internet interface to be in other network segment, ICS always work,
magically.

As I said, when I enable RRAS / NAT, instead of ICS, the only difference is
that default gateway of WAN/PPP interface is blank

Yes.. when I enable RRAS, only server con browse internet, but LAN computers cannot.

Besides difference I write about default gateway, if I pathping from a LAN computer, I get this response:

2.- With RRAS enabled (the non-working case)

Tracing route to www.l.google.com [64.233.161.104]
over a maximum of 30 hops:

It seems default gateway is affecting the route from 192.168.0.1 to 200.119.235.1

Thanks

Thank you for the update.

can I also assume that the server can access the internet but no comuters behind the NAT? I had one case like this but can't remember the solution. is some things to do with DLS and windows NAT. Which DSL model do you have? some details of DSL configuration may help.

Robert,

I don't have static IP. Each time I connect to my ISP, it assigns me a new
IP (I connect to my ISP through a DSL router connected to a NIC in the
server). That's why I cannot set default gateway manually using Network
connections.

I wonder, the same as you, why DHCP enabled appears No.
