I think we are having problems with the configuration on our SonicWall and so I am trying to put together a cisco to act as a firewall and do nat but I am not sure how to go about it or if I even have the appropriate hardware to accomplish this.  Here is the scenario.

RouterA ISP1 (Cisco 1700)                            RouterB ISP2 (Cisco 1700)
Serial0 63.243.x.x                                        Serial0 72.2.x.x
FastEthernet0                              FastEthernet0

                               Currently both hook to a SonicWall Pro2040 but...
                               this is how I want to try it...
                                      RouterC (Cisco 1700 with 3 eth ports)
Can and how would RouterC handle simple firewall and nat of both T1's coming from RouterA and B?  This way I can have a nat pool specifically go out through a certain ISP and then nat incoming from either ISP.  I'm thinking the Ethernets on all routers have to change to routeable ones but please give me some sugestions.

Thanks in advance,
