I am trying to configure FWSM on the 6500. The connection from the service provider via layer 2 trunk on the 3750. VLAN 3692 for the internet and there is layer 3 interface on the 3750 like 18.104.22.168 255.255.255.252. I did connect from the 3750 switch to one of the port and configured as switchport access vlan 40 which is my outside vlan interface. I can not communicate anything on the 3750 or outside. Please anybody can help on this.
