MSR2004-24 Routing noob

[chipset5280]

My config is posted below, please be gentle. This is my first attempting to configuring an HP router. 

I have computers connected to ports GigabitEthernet0/2 and GigabitEthernet0/4 with IPs on the X.X.X.X and I.I.I.I subnets respectively. My laptop connected to GE0/2 can ping into the laptop on GE0/4 and appears to be working perfectly. 

The laptop connected to GE0/4 can ping the Vlan-Interface20 but not the GE0/2 interface and not the laptop connected to GE0/2.

Almost needless to say, I need to be able to route traffic in and out if at all possible. :) Any assitance would be greatly appreciated. Thanks in advance.

Hello,

This could be due to persistent route in device connected on gi0/4
