Inter Vlan routing on switch ports on Cisco 877 Router

I have a Cisco 877 router which I want to use as a Switch only in conjunction with netflow.
I have configured as below.

I have a PC plugged into fe1 with an IP of 192.168.20.100

I have another PC plugged into fe0 with an IP of 192.168.1.100

I can't ping the PCs from either end.

I can ping 192.168.1.234 from the PC in the 192.168.20.0 subnet  but not the 192.168.20.1 from the 192.168.1.0 subnet which means some sort of routing is working.

Frankly i'm stumped!

Any ideas?

Regards,
