Cisco 871 Routing Problem

Hi Experts,
I am preparing a Cisco 871 router to interface between 2 subnets as follows:
VLAN1 : 10.10.10.0/29 on fe1(10.10.10.1) : Used for Router administration only
VLAN2:  192.168.0.0/24 on fe0 (192.168.0.253):  Subnet 1
VLAN3:  192.168.16.0/24 on fe2(192.168.16.253): subnet 2
fe4 is disabled.
Connected to VLAN2 and VLAN3 are 2 PCs named PC0 (192.168.0.2) and PC16 (192.168.16.2) respectively.
From within the Router (via telnet) I can ping fe0,fe2, PC0, PC16.
From PC0 I can ping it's respective interface on the Router (fe0).  The same is true for Pc16.
However I cannot ping PC0 from PC 16 and vice-versa.   The running config is below
Thank you for your help

Cisco Router and Security Device Manager (SDM) is installed on this device. 

This feature requires the one-time use of the username "cisco" 

with the password "cisco".
 

Please change these publicly known initial credentials using SDM or the IOS CLI. 

Here are the Cisco IOS commands.
 

username <myuser>  privilege 15 secret 0 <mypassword>

no username cisco
 

Replace <myuser> and <mypassword> with the username and password you want to use. 
 

For more information about SDM please follow the instructions in the QUICK START 

GUIDE for your router or go to http://www.cisco.com/go/sdm

PC0 has a default gateway of 192.168.0.253 and PC16 has a default gateway of 192.168.16.253, right?

Hi JFrederick29,

The gateways SHOULD have been set s you suggested.  I thought that they were.  I was wrong.  When I corrected the settings everything worked like a dream.  Thanks for the solution.
