InterVLAN routing issue

Simonlee2112
Level 1
Level 1

Hello, i am having trouble getting 2 PC to ping each other on 2 differnent vlans that i have set up on my cisco 3750x

there is vlan 10 - ip address 192.168.10.1 

PC1 that is connected to this is 192.168.10.2 - 255.255.255.0 - 192.168.10.1

and vlan 20 - ip address 192.168.20.1

PC2 that is connected to this is 192.168.20.2 - 255.255.255.0 - 192.168.20.1

i have got ip routing enabled

From the switch i am able to ping all devices

When i turn the windows firewall off PC1 is able to ping PC2 but when it is turned back on even with file and printer sharing enable the ping requests time out.

What firewall exception do i need to enable in order to get ICMP working? incase there is something i havent done in the switch the running-config is below

You may have a firewall software on your PCs installed/enabled that is blocking ping.  Disable the firewall and try again?
