The describe her the structure of my net: centerstar catalyst 4006 Cisco and connected to the center it adorns with stars 8 Switch 2950 Cisco.

The initial addressing of the net is the following:
Net 10.5.66.0
Subnetmask 255.255.255.128
Gateway 10.5.66.122

The Gateway (10.5.66.122) it is to Firewall, to which to router is connected, for the access toward and from the outside.

The have created the following VLANs breaking the plan of addressing,:
VLAN 1 (default) 10.1.1.100 255.255.255.0
VLAN 2 10.5.66.1 255.255.255.192
VLAN 3 10.5.66.66 255.255.255.224
VLAN 4 10.5.66.97 255.255.255.240
VLAN 5 10.5.66.113 255.255.255.248
VLAN 6 10.5.66.121 255.255.255.248

The have setup the door of the Firewall (3/18) in the VLAN 6.
The have performed the commands:
ip route 10.5.66.0 255.255.255.0 10.5.66.120
ip routing

With such configuration, from any VLANs, succeed to pinging the address 10.5.66.122 but it don't allow me to go out.

The attach the configuration.

You could lend me to hand.
Thanks for the attention.

Why do you route everything to 10.5.66.120, shouldn't it be 10.5.6.122

I perform the routing to ward the subnet (or VLAN 6) you contain the address of the gateway toward the outside.
It is not correct?
Why I succed to ping the station gateway but not the outside?

You excuse for my english. I am Italian and I chew it little.
