Here is my Scenario.
I have two subnets on a point to point T1. Each is divided by a Cisco 1721 router. On the one side of the T1, there is a Netscreen firewall which is an Internet Gateway. My objective is to have both subnets communicating, and also the subnet opposite the firewall to be able to access the Internet by only using their router as the gateway.
I will be using HDLC encapsulation on both ends. I will also be configuring DHCP on the router on the 2nd subnet, as there are noservers located there and I would rather do this than create a dhcp relay agent. I will be excluding the first 20 for expansion if servers come into play in the future.
IP Addresses:
Router side 1: 192.9.200.1
Netscreen side 1: 192.9.200.2
Router side 2: 192.9.201.1
Here is my proposed configuration:
Side 1:
interface FastEthernet0
ip address 192.9.200.1 255.255.255.0
speed auto
!
interface Serial0
ip unnumbered FastEthernet0
!
ip route 192.9.201.0 255.255.255.0 Serial0 (To other side of p2p)
ip route 0.0.0.0 0.0.0.0 192.9.200.2 (If not to 201 subnet, to Netscreen)
##################################################
Side 2:
ip dhcp excluded-address 192.9.201.1 192.9.201.20
!
ip dhcp pool default-pool
network 192.9.201.0 255.255.255.0
dns-server 192.9.200.5 192.9.200.10
default-router 192.9.201.1
!
interface FastEthernet0
ip address 192.9.201.1 255.255.255.0
speed auto
!
interface Serial0
ip unnumbered FastEthernet0
!
ip route 0.0.0.0 0.0.0.0 Serial0

What do you think? Yay or nay? I will be doing this remotely via console and the customer will be plugging them in themselves, so I would like to get this right the first try.
Thanks in advance!
