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
