Could you possibly explain in more detail. I would really appreciate it. As
for our setup. WE have ONE PM3 on our side ISP running RIP and a cisco 2501
and serveral NT and Linux servers. WE have 2 class C's 209.90.15.0 and
209.90.13.0 I have subneted 209.90.13.0 to one customer givving hime 32 IP's
with a netmask of .224 ip's 32 - .64 I now have this new customer that needs
about 50 IP's I tried to just give them 2 subnets from the 209.90.13.0 class
C. I could not get the second subnet to work with the first subnet or access
the internet even though I applied a second IP to the pipeline 50 witch is
there router two th ePM3. There setup is all NT servers and win95/98
machines. I setup DHCP on the PDC also setup wins. I installed a second NIC
in this machine so it would have an address on each Subnet. It assigned IPs
as expected but again the machines in the upper subnet could not access the
internet though the pipeling 50. So I installed RIP on this NT machine with
2 nicks and set it up as a router. This did nothing. I am stuck at this
point. I believe I can setup a route to get to this second subnet via the
cisco if I need to but I cant get the Customers Network to function
properly. Any more help would be great thanks.
