Newbie trying to turn a 1721 into a Bridge

[Falken0000]

I want to simulate a connection from my office in NY to CA. We will eventually be using a frame connection. In the meantime Boss wants us to test in a mock environment.
We have a 1721 with a 1enet WIC.
I assigned Fastethernet0 10.1.0.10 and the inside ethernet0 address 10.4.0.1. From my desk which is 10.1.5.123 i can ping 10.4.0.1 but nothing on the network past that. I have 2 servers behind that on a hub and can't see them. I want to setup the 1721 as a bridge and I must be doing something stupid and can't seem to get past this point here is a copy of the config:

Any help would be much appreciated

Whats the CIDR of the addresses (Subnet masks)?

 

[chieftan999]

Sorry. I have just realised you are using a default class B.

I assume your PC is connected to the FA interface due to the IP scheme?

You are being able to ping the Ethernet port.

What is the address scheme and the subnet mask of the servers?

The servers before the router are
10.1.0.0 and a sub of 255.255.0.0

and behind this router the servers are 10.4.0.0 and a mask of 255.255.0.0

I just want this to act like a bridge.
I can ping the 10.4.0.1 from before the router just fine, I just can't get 10.4.0.2 which is an IP of one of the servers behind the router.
