Multiple Public IP's on a router. How to?

I've seem to forgot everything I once knew or thought I knew. I can't find it in my books either.

We have a 2811 router connected to our ISP via a bonded T1 with one IP assigned to that interface. Our other interface, FE0/0 has a block of 6 public IPs. I want to connect a PC to FE0/0 and assign it the next available public IP. I can ping from the outside world to the bonded T1 IP and the FE0/0 IP, but not the PC. Does anyone have a sample config of utilizing a fast ethernet interface with multiple public IP's and one of those IP's assigned to a directly connect PC? (no NAT).

The PC is only for testing purposes. The first 3 octects below were changed for posting purposes.

interface FastEthernet0/0
 description Fe0/0-to-TestPC
 ip address 212.55.124.113 255.255.255.248
 duplex full
 speed auto


Here is the output from my router tracing to the PC.

2811#sh ip route 212.55.124.114
Routing entry for 212.55.124.112/29

The PC has a default gateway of 212.55.124.113, right?

JFrederick29 - Yes, the PC has a default gateway of 212.55.124.113. The PC pings  212.55.124.113 (the default gateway) are successfully. But from the defaultgateway router i can't ping the PC.

Windows Firewall Services are disabled. The PC itself is a fresh image. No AV or Updates or SPs. Just Server 2008R2 SP2.

On the router, if you do a "show arp", do you see the IP to MAC address mapping of the PC?

Actually, I don't see the IP to MAC of the PC. I do however see it for the F0/0 interface the PC is connected. Internet  212.55.124.113          -   001a.a142.9fb8  ARPA   FastEthernet0/0

I utilized another OS that wasn't server 2008 R2. It responded right away. I guess even thought Windows Firewall Services was disabled on Server 2008 R2 that something else on the OS was preventing pings from replying..
