Routing public subnet trough WAN-interface Cisco C921 router

Hello,

Can someone please help me. We want to configure the following construction:

                                                                                                     /---> (Palo Alto) <-----> LAN

Fiberswitch(ISP) <-----> (C921router) <-----> (8p-switch) <---                 |

                                                                                                     \---> (Palo Alto) <-----> LAN

 

We have x.x.x.169/29 public IP-adresses from our ISP. We need to setup a PPPoE connection on the C921 router that gets the first IP-adres in the public subnet (x.x.x.169/29). After that, all devices on the other interfaces from the C921 router must be able to access the internet using the x.x.x.169 addres from the C921 router.

(NOTE: Palo Alto's will get the x.x.x.170/29 statically assigned with the x.x.x.169 as the next-hop / gateway).

All other devices (like a laptop) must get an public IP-adres from that subnet x.x.x.169/29 as wel when connected to a interface from the C921.

Is this possible to configure. And if so, how? Because I don't know how I can route/forward traffic from the Palo's (that are connected on for example interface 0/1) to the public IP-adres on the router (.169). (NOTE: There will be no IP's configured on the other interfaces exept from the uplink interface to the ISP switch).

Thanks in advance,

Jeffrey
