Configure Cisco Router 2610

My ISP gave me a Routing Network Default Gateway of 71.69.49.48 255.255.255.248. They aslo gave me 71.69.49.128/25. that is routed to 71.69.49.52.  My quesstion is, how do i setup the router to route my 71.69.49.128/25 traffic.  I have a cisco 2610, with 2 FastEthernet ports.

I don't want to NAT public to private ips, just want to use a gateway of 71.69.49.254 on all servers so they keep the public ips.

Configure one of the Ethernet ports with the WAN IP (71.69.49.52/29) and then configure the other Ethernet port with 71.69.49.254/25.

conf t
int fa0/0
ip add 71.69.49.52 255.255.255.248
no shut

int fa0/1
ip add 71.69.49.254 255.255.255.128
no shut

ip route 0.0.0.0 0.0.0.0 71.69.49.49    <--ISP gateway

Then simply plug the Fa0/1 interface and the servers into a switch.  You can then address the servers with a public IP and set the gateway to 71.69.49.254.  Your ISP will route the block to your WAN IP.

Routing is disabled, do this:

conf t
ip routing

.49 is the IP your ISP provided as your gateway, right?  and they told you to use .52 on the WAN side?
