On firewall, the DMZ2 port connects to ColoC3750X switch on Gi2/0/21 while the LAN port to Winston-3750sw switch Gi1/0/1, as shown on the attached diagram and the config files. There is a trunking connection between the two switches.
The big big issue is, from the ColoC3750X switch, we are NOT able to ping the DMZ2 port IP 10.10.2.1. (But from Winton-3750sw, we are able to ping both 10.10.2.1 and 10.10.2.2.)
Can you please figure what I missed out?
